This was my best selling item at the Guild of Book Workers Conference a few months ago, and is new for this year. Perfect for intricate cuts in tissue and paper. Paper conservators love it for infills. Artists love it to make stencils. And everyone loves the cleaver design that retracts completely into the standard supplied .9mm mechanical pencil handle. Order your micro knife for only $35!
A delrin hera rapidly becomes indispensable for many bookbinding and conservation tasks. I use it to gently turn leaves of fragile books, delaminate hinges of matted artwork, hold leaves down during photography, insert adhesive into bent book corners, score tissue for dry tearing, and to pry apart covering material when rebacking. But you won’t pry this beauty out of my hand. Get your own delrin hera for only $45!
Bookbinders likely know that linen thread is classified by a two number system, such as 35/3. And most know that the second number represents the number of threads plied together, and the first number how thick or thin the thread is. But what does the first number actually refer to?
It turns out that two different systems, an English system and a Metric system that use a similar two part description of size separated by a forward slash. However, these two systems are not the same. Most thread sold by bookbinding supply companies uses the English System.
I’m still not sure what system the Londonderry Linen Lacing Thread in the image above uses. It is labeled only a mysterious “#4”. I love sewing with this thread, though, since it is thick, soft, easy to untwist, tangle free without waxing, and remarkably compressible. It is possible to sew a book naturally packed with it. It consists of five plies, and is roughly equivalent to a 20/5.
If you are wondering what size thread you should use to sew a book, check out my Guide to Swell.
Finally, Colophon Book Arts is a reasonably priced, one stop shop to purchase a wide variety of sewing threads.
Cor Knops, of Knops Boekrestauratie in the Netherlands, kindly sent me these images of some antique thread he owns.
These packages contain hanks of thread, and all weight about a pound. I think the package on the left is 25/3, and on the right 12/3. So if my calculations are correct, the 12/3 should contain 1200 yards of thread, assuming a 12/1 would contain 12 – 300 yard skeins = 3600 yards. Enough thread for a lot of books in any case!
It has been quite a while since I vended at the Guild of Book Workers Standards of Excellence, so I decided to pull out all the stops this year and start to sell off some of the used tools and books I’ve collected over the years. Of course, all the new tools I make will also be available to inspect, test drive, and purchase.
You don’t have to be registered for the conference to attend. The Lowes Philadelphia Hotel is the venue in downtown Philadelphia, and vendor hours are Thursday October 24, 10 – 6, Friday 8 – 8, and Saturday 8 – 3:30.
I’m also bringing a huge bargain box, filled with used bookbinding related tools: Starrett dividers, weights, knives, some prototypes of tools I currently make, a few older versions of tools — kind of a garage sale, really! All super discounted.
Even if you don’t want to buy anything, please stop by to say hi! It is always fun for me to meet those who read this blog.
