With Büchertiger Supplies I founded the shop which I would have wished to find when I started out binding books. Especially coloured linen thread was very hard for me to find in the beginning, and it took me a long time to search for suppliers. I then found out that I had to buy largely in bulk – and thus a business was born. I first sold excess and soon bought to sell.

I put a strong emphasis on customer service. I enjoy helping customers to choose the thread that is right for them, and love to hear about their projects.

Beside thread I also stock parchment pieces, ideal for training both caligraphy and small parchment bindings.

Well, so let me show you my most important stock – the thread! You can order via email or telephone, or just head over to my Etsy Shop where you also can see the prices.

Gruschwitz WMZ, NeL 18/3Z

gruschwitz goldgelb 01This German linen thread is firmly twisted and then calendered which makes it strong and gives it a faint sheen. It is not waxed. It is advisable to wax it by hand (actually it can be machine waxed if you have such a waxing machine) before using it to sew leather.
If you are going to use it for bookbinding you probably will want to wax it, too. With some experience, it can be used non-waxed for smaller volumes which for open spine bindings has the advantage of no wax on the outside. This is an advantage since wax attracts dirt and dust like a magnet.

There are 20 different colours available from Gruschwitz. Most have a beautiful, natural greyish-ness to it, characteristic of only mildly bleached threads.

Somac Thread 4/18 and 3/18

This linen thread, produced in England, is the newest addition to my stock. It is available in 4-ply and 3-ply, is non-waxed and of very high quality. It has not been calandered like the Gruschwitz thread which gives it a matte finish and makes it softer than other bookbinding threads in my stock.

It should be waxed before sewing. If you are going to use it to bind books you probably want to wax it, too, because the wax makes the thread on the one hand slightly sticky, which makes it easier to makes knots and looks, at the same time it reduces fraying and accidental loops. However, with a bit of practise it can be used as it is, which has some advantages, especially when you are sewing exposed bindings where the wax on the thread might otherwise attract dust and dirt.

There are 12 colours available of the 4-ply thread, and unfortunately only 9 of those also for the 3-ply.

Crawford’s Waxed Irish Linen Thread

waxed packCrawford’s waxed Irish linen thread is used like all linen threads for a variety of traditional crafts, including leather sewing, bookbinding, and all sorts of crafts that include knotting (like macrame and basket weaving).
It is by many considered the best thread for Coptic bindings. The 4-ply is most often used, but it is available also in different thicknesses.

I have the largest selection of colour in the 4-ply range, but also a small selection of 3-ply, 7-ply, and 12-ply threads. The latter is interesting to use as sewing support rather than for sewing thread. Before using it, it is advisable to run it between your fingers several times to get rid of excess wax and to give a smoother finish and thread.

The wide range of different colours is the main advantage of this thread in my eyes. With broad selection of bright colours to choose from, it is rare not to find a match. Some of the colours in my shop can’t even be found in other stores, like coffee and dark moss.

Goldschild Line Thread, NeL 18/3

goldschild gruentoeneThe Goldschild line thread is advertised as Londonderry thread in the US and there only sold on 30m spools. I carry the 25g spools, and the whole range of 26 colours in thickness NeL 18/3.

Goldschild thread is not as tightly twisted as the other linen threads in my range, and therefore feels softer. It cannot be broken by hand but has to be considered weaker, especially since the weaker twist makes it more vulnerable to abrasion damage.

When waxed before usage, it holds up reasonably well for sewing books. However, due to its weaker structure, I can only recommend it for light (one or two section) bindings, and for stab bindings like an Asian binding. It would be suitable for sewing headbands, though, and could be a really nice touch on a rustic book for which silk thread doesn’t quite seem to match the style.

Goldschild thread is a top choice for as a crochet or embroidery thread. The thread is not suitable for sewing leather.

Fil Au Chinois, Lin Cable

sheenAh, lin cable, the most lush among the linen threads. This thread has been cabled, which means it has been twisted twice. This makes the thread especially even and round and enhances abrasion resistance and strength in general. When viewed from very close it looks more like very fine rope rather than thread (that’s the look of the cabling).

It is thinly waxed before cabling which gives the thread its luxurious sheen whithout making it the slightest bit sticky.

Without a doubt this is the best thread you will find for creating leather products. Like other linen thread it can be used whereever a strong thread is needed. – For example for creating puppets on a string, just to name one. And of course it can be used for bookbinding. As it is so especially strong, it is not suitable for conservation work.

The thread is produced in 5 different thicknesses, I currently stock 25 colours in their two thickest calipers (called 332 and 432), and a small variety in the thinner 632. I am planning to expand the range of available colours and thicknesses slowly over the next time.

Professional Bookbinding Thread

bookbinding thread etsy 01I am stocking professional bookbinding thread from two companies: Gruschwitz (Germany) and Fil Au Chinois (France).

Both are 100% twisted linen thread, made from the longer line part of the flax fibre. This thread is suitable for conservation work, and meets the highest requirements. The Fil Au Chinois thread is available in the thicknesses 12, 20, and 30 which are internally used numbers. The thread is thicker if the number is lower.

The Gruschwitz thread is available in the thicknesses 14, 18, and 25. The numbers here are logically arranged: the 50g spool of the No. 14 thread has approximately 140m, the No. 18 has about 180m, and so on.

This thread should be hand waxed before usage.

Fil Au Chinois, Fil de Lin

etsy 03This French linen thread is a pleasant simple kitchen thread. It is sold in 30m balls in only this one white colour. It is food safe, and can be used to tie up meat, cabbage rolls, or whatever you need to tie and then cook. Apart from kitchen use it is good for all kinds of uses, from building kits to wrapping gifts. It is probably the strong thread your mother or grandmother had in that drawer in the kitchen.

It is produced in three different thicknesses which I all stock.



Linen Cord

linen cord 12ply 02This rustic linen cord is suitable for sewing support. It is 12-ply, non-bleached and without any additional finish.

Simple goodness for a medieval look.

Currently only sold in pieces, no whole spool available.



Everlasto Jute Twine

This Everlasto Jute twine is relatively coarse and available in 5 different colours. One spool has approximately 50m. It is made of 100% jute which is a natural fibre which makes the thread biodegradable. It can be used for all kinds of knotting and binding in the garden.

I also use it for book cords, and for crocheting things like containers and coasters.



Fil Au Chinois, Lin Retors

alle 03 kleinerThis 3-ply waxed linen thread is usually too thin for bookbinding (diameter approx. 0.43mm). But I use it for miniature bindings, where it is perfect. It is also suitable for beading.

Its intended use is for sewing anything that needs a strong seam, from sewing on buttons to sewing heavier materials like jeans or leather clothing. This thread is not suitable for use in a sewing machine.

It comes in a wide variety of colours of which I currently only stock eight.
