How much rope should I buy?


When it comes to ropework, the best way to cripple your creativity and flow is to not have enough rope.

Regardless of your skill level, you should have enough rope to:

  1. Complete the tie you intend
  2. Complete the tie even if a bundle snags and you have to set it aside
  3. Be able to add some rope if you feel creative

If you're using your rope for shibari, your ropes should also feel identical in your hands, because different ropes will throw off your rhythm, especially if you're tying in a dimly lit room. Thus, ropes should be identical in diameter, length, rope endings, etc.

If ropework includes transitions (starting one tie, changing it, then performing a different tie), you'll need extra rope.

Your tying will be faster, look better, and feel better if you can keep using fresh rope bundles. Both you and your partner will appreciate not having to stop untangle used ropes partway through a scene.

If you use every last rope you own for your ties, you don't have enough rope.

Finally, if you aspire to be a better rigger, don't buy rope for your current skill level. Buy enough rope to be the rigger you want to be.

What length of rope should I use for shibari?

Have you ever untied a knot in the middle of a really long rope? If so, you know how do so forces you to pull rope, pull rope, pull rope, and pull more rope. It's boring and it takes ages

Far too many shibari riggers use rope that's too long. As a result, they spend so much time pulling rope that their ropework looks boring. Worse, to the person being tied, it feels boring.

Japanese shibari masters use 7 m ropes (23 feet). However, many Western riggers use rope that's 8 m (26.2 feet) or even 10 m (32.9 feet) to "fit" Western subs who tend to be larger than typically shorter and thinner Japanese women.

While it's true that Westerners are taller, rope lengths should be based on the size of the rigger, not the rope sub. Specifically, rope lengths should be based on the arm span of the rigger.

In exact math, the distance of each rope pull is the distance between the rope where it leaves the rope sub's body and rigger's shoulder, plus the length of the rigger's arm. In practice the average distance is the same as the rigger's arm span. A second pull with the other hand yields another arm span worth of rope, for a total of 2 arm spans.

The Handbook of Adult Anthropometric and Strength Measurements gives the mean fingertip-to-fingertip span of people from various countries:

  • France, female: 1600 mm
  • Netherlands, female: 1635 mm
  • Sweden, female: 1640 mm
  • UK, female: 1674.7 mm
  • USA, female: 1681.6 mm
  • Japan, male: 1703.8 mm
  • France, male: 1765 mm
  • Sweden, male: 1790 mm
  • UK, male: 1828.7 mm
  • USA, male: 1834.2 mm
  • Netherlands, male: 1845 mm

These statistics tell us that average females from the tallest countries have a shorter armspan than average Japanese males. Men from the tallest country, Netherlands, have longer average armspans that are only 141.2 mm longer (5.6 inches).

Most people don't know their armspan, but it's roughly equal to your height. The average Japanese male has a height of 1686.8 mm (5 feet 6.5 inches).

Japanese riggers use 7 m ropes. Thus, if you're shorter than 1686 mm (5 feet 6.5 inches), there's no question that you should be using ropes no longer than 7 m.

A 7 m rope to a person 1686 mm is proportionate to an 8 m rope for a person 1926 mm tall (6 feet 4 inches). Thus, if you're 1.93 m (6'4") or taller, an 8 m rope should be fine.

<id="ropetypes">

 If you're somewhere between 1.7 m and 1.9 m (5'7" and 6'3"), the division point is less clear. 

I did some tests with friends of various heights and found that those 1.78 m (5'10") and shorter clearly benefited from using 7 m rope. However, if you're aiming for speed (and that's the best reason to buy jute), err on the side of shorter rope, rather than longer.

1.79 m and above (5'10"+)

 

These rope lengths are recommendations based on my research and experiments for efficient shibari rigging. 

Enough Western riggers choose 8 m rope that I offer it as a standard length. However, I because I believe more people would benefit from 7 m ropes, I offer Douglas Kent Lightning 7 at a proportionately discounted price. 

Finally, whether you prefer a standard length or not, you can design ropes that exactly suit you by ordering Douglas Kent Custom rope.

What’s the difference between natural jute and blond jute?

 

We offer a mind-boggling number of customizations to our rope, but we don't want you to have a hard choice for the rope itself.

So we only offer the best jute we could find.

Natural jute and Blond jute are the same rope. Blond jute is treated to lighten the color; the treatment slightly affects its mass. However, even with side-by-side comparison, the differences are almost imperceptible, even under magnification.

For all intents and purposes, the only functional difference is color; your choice of treatment will have a greater effect on the handling properties of the finished rope.

Both ropes are great. Both ropes handle beautifully. Just choose the color you prefer.

* Natural jute and Blond jute are the exact same rope. Blond is treated to lighten the color. The process reduces some of the mass.

** The diameter of twisted jute rope is deceptively difficult to measure, even with highly accurate digital calipers. The "three-circle" cross-section of 3-strand twisted rope inherently defies accurate diameter readings. Further, jute has a compressibility that greatly increases measurement variability.

Being a natural product, jute has a much higher production variability than synthetic ropes (which are extruded in continuous monofilaments, then spun). Jute imperfections, twine extensions, natural variability, and jute's hygroscopic nature tend to produce thicker (but rarely thinner) sections of rope.

Thus, the rope diameter is nominal

† The process used to lighten the color of the jute from Natural to Blond also physically reduces the mass by about 3.8%. However, the difference is almost imperceptible, even with side-by-side comparison. The choices you make for treatment will have a far greater effect on your rope's handling qualities. In practice, Naturaland Blond ropes are identical, but for color.

‡ Jute is highly hygroscopic and able to absorb up to 30% of its mass in water, without feeling wet. The jute is measured in a low humidity environment of about 20% RH. As jute absorbs water from the atmosphere, the mass will increase. Both Natural and Blond absorb similarly, thus at higher humidity, the percentage difference in mass should decrease.

<id="finishing">

 

How is the rope finished?

 

Whipping (center marks)

Center marks are whipped using only thread.

Each center mark is wrapped four times, then cinched three times - once between each of the three strands.

To terminate the whipping, we knot the ends not once, not twice, but three times, then tuck the knot into the core of the rope.

The result is a whipping that holds the rope securely and resists lateral movement.

 

Whipping (end knots)

Unlike most rope vendors, our knotted ends are always double-whipped. A double whip on a knotted end provides extra security and ensures that your beautiful decorative knot won't loosen.

Each double whipping is created with a continuous thread. The first whipping is applied on the rope side of the end knot - the rope is wrapped four times and cinched three times, once between each of the strands. Then, the thread is passed through the center of the end knot and the whipping is repeated on the other side.

A double-whipped end knot makes the knot more secure; our double whipping with a continuous thread ensures that the knot is secure, and that the whipping itself cannot pull apart or slide off the tassels of the rope.

<id="measuring">

 

How is the rope length measured?

 

Douglas Kent Rope measures its ropes from inside the knots.

We feel that the inside-the-knot length best represents the usable length of the rope.

If we measured unfinished length, then adding any end knot would shorten the rope below its advertised length. Worse, different end knots would make finished ropes inconsistent - some end knots require a significant length to create (and significantly different from other knots).

Our inside-the-knot length helps keep different sets more consistent with each other.

However.

Jute rope is a highly hygroscopic natural fibre. Jute is so hygroscopic that we've observed a 5% gain in mass occur in two hours, due only to a 20% change in relative humidity. The gain in mass shortens the rope length by about 1.5% (or about 12 cm on an 8 m rope).

Now, you've probably never noticed this issue or heard about it from other jute suppliers. We discovered it after investigating why ropes were failing our quality assessment tests. But without a dedicated measuring station, a 100% +1%/- 0% measuring tolerance, and QA tests, the issue wouldn't have been noticed.

We store our rope in low humidity, so our measurement tolerance helps ensure that your inside-the-knot length is always slightly more. However, unless we greatly exceed the stated length, high humidity will shorten the rope below the advertised length. (By contrast, the ropes of most other manufacturers are always shorter than advertised.)

Thus, when you order 40 m custom rope, made into five 8 m lengths, we actually give you a few metres extra. If you order ropes that don't quite add up to 40 m, we don't process or ship the scraps.

When you order 40 m of raw rope, we ship the exact measured length, with extra tolerance to allow for humidity changes.

When will Complete Shibari 3: Stars be released?

This is the most frequent question I get asked, by far. The short answer is that Complete Shibari 3 already exists. Sorta. What follows is the full answer.

After finishing Complete Shibari 1 and 2, I immediately set to work on Complete Shibari 3. At the time, I had perhaps 20 pages of content.

As I wrote, Complete Shibari 3 grew until I split it into Complete Shibari 3 & 4. Then it grew into three separate books. Then four.

Most other authors write one book. Then, if it gets popular, they rework the original content for a second book, then a third, and so on. It's a fast, easy way to release many books, but you're not really getting much with each new book.

My books cover different areas of expertise, feature content not available anywhere else, and have as little repetition as possible. They also have a higher information density than most other books of any type. However, creating them takes vastly more effort than writing a novel - at least 20 times the effort. This is where money comes in.

The kink book niche is very small - virtually no other authors can subsist on the income from their books. By self-publishing, I've been able to, but the harsh reality is that I'd earn much more if I worked a regular day job in my field.

I've got many partially written books ranging from 30-80% content complete. However, turning that content into well-polished, tightly integrated finished books usually takes months of uninterrupted concentration and effort.

After a massive effort (even by my standards), I released Rogue Hojojutsu. Rogue Hojojutsu fulfills my promise to include Hojojutsu in Complete Shibari 3, except that it's an entire book. I'm incredibly proud of the book and sincerely believe it's the only Hojojutsu book that lets you actually learn complex Hojojutsu ties from scratch.

Feedback on Rogue Hojojusu has been very positive, but sales have not, even from core rope enthusiasts. Since I can't afford the risk of investing years of effort in another book with similar sales, I've reluctantly diverted my energy towards other projects that provide more reliable income. Now, part of this is my fault - I'm terrible at self promotion. But if I were more interested in self promotion, I'd have written a throwaway pop psychology diet book or something. The trait that makes me terrible at self promotion is also the trait that makes me willing to toil for years on very niche books that will never sell in massive numbers.

When Harry Potter and the Deathly Hallows came out, it sold 50,000 units. Counting Amazon only. Per hour.

If any of my books sold 50,000 copes in two years, I'd have already published the nine books I have in production. And I'd have done so without compromising the quality of the books, too.

So yes, Complete Shibari vol 3, part 1 of 4 is out. It's called Rogue Hojojutsu. I want to release Complete Shibari 3 parts 2, 3, and 4, and much more, but I need support. Now it's your turn.

Support the hell out of Rogue Hojojutsu. Buy a copy, even if it's not exactly the book you were expecting - it'll make your shibari better. Tell people. Review it. Show it to friends. Buy copies for friends. And buy rope.

A bit of support from a lot of people goes a long way. And in a small niche, your support counts.

How will my rope be packaged?

Your Douglas Kent rope is shipped in an 80 micron thick polyamide/polyethylene (nylon/plastic) vacuum-sealed bag that protects it from water, air, and other contaminants.* Prior to processing or sealing, we store your rope in a low-humidity environment.

* Also snow, sleet, wind, dirt, mail carriers, rain and most dinosaurs.

 

Included in the vacuum-sealed bag are two packets of silica desiccant to provide additional protection from moisture. Each packet of silica desiccant is rated for protecting up to 1 kg of material (about six 8 m ropes). Douglas Kent Rope always provides enough desiccant to exceed that requirement.

Your vacuum-sealed rope is then carefully wrapped in a layer of heavy black paper and sealed with a simple obi bow (kimono bow). It’s ready for gift-giving right away (or just gift-receiving)!

We use a plain white poly mailer bag to provide discretion and added protection from outside moisture. Our return address on the package is “Little Known Fact Sdn. Bhd.” and the customs label simply says “jute rope.” There are no logos or branding on the outside of the package.

To take advantage of a faster shipping speed, your order may arrive in split packaging. We will always label your packages with “Package 1 of 2” or “Package 2 of 2” so that nothing gets missed.

 

Back to top

 


 

How will my books be packaged?

Your books are discreetly packaged and well protected during shipping.

Books are enclosed in a 1mil poly bag, then wrapped in a cardboard "book burrito" before being sealed in a standard USPS padded envelope. The packaging helps keep your books dry, flat, and well-defended from velociraptor attacks.

The return address on the package simply says “Customer Service.” The customs label says “craft book set.” We don’t put logos or branding on the outside of the package.

Why does tracking show my package not moving?

If your order is being shipped from another country, tracking may show a flurry of activity and then just stop...

8 days ago
8 days ago
9 days ago

Item dispatched to New York NY (USPS)
Item processed at MPC PMIH (KLIA)
Item dispatched out MPC PMIH (KLIA)
Item processed
Item posted over counter

The example above shows a package of rope mailed from our headquarters in Malaysia being tracked to a major airport, KLIA (Kuala Lumpur International Airport), then flown to New York. However, because the package is now in the care of the USPS (United States Postal Service), no further tracking updates will appear. With roughly 200 countries throughout the world, it shouldn't be surprising that each postal service has their own tracking system and that they're not compatible with each other.

The lack of updates is frustrating, but the package is still moving.

We've been shipping packages internationally for over ten years. After thousands of shipments, we've found that packages are often late. Really often.

International packages pass through a dozen buildings and many airplanes. Customs often adds serious delays, particularly for countries that practice security theater or require excessive paperwork (we're looking at you, Germany). Peak shipping periods and holidays vary greatly by country - Christmas, Chinese New Year, Ramadan, etc, can each shut down government for a week or more.

Because shipments are so frequently delayed, virtually no shipping company will even consider beginning a search until the delivery window has been exceeded, usually by a few weeks.

So yeah, packages are often late. But after more than a decade of shipping internationally, we've been amazed to find...

Packages are almost never lost.

It's amazing, but despite all the travel, delays, and processes, somehow the vast majority of packages reach their destination.

So relax and know that, while your order may have gotten delayed and tracking isn't updating, it will still arrive.

Before emailing about missing packages, see "How long will my order take to arrive?".

Why did I only get half my order? 

Books are shipped from USA; rope is shipped from Malaysia. Thus, orders for books and rope will always arrive in two packages.

However, due to quirks in shipping fees, it often makes more sense to send two smaller packages for larger rope orders. These price breaks commonly occur at 1 and 2 kg.
