Because of its strength linen thread is used to sew signatures in book binding. It is often lightly waxed with Beeswax (S289).12/3, 18/3, 35/3. The first number is the thickness of the thread. The higher the number, the thinner the thread. That is 12/3 is thicker than 18/3. The second number is the number of strands that are twisted together to make the thread. 12/3 has three strands. (Flax and linen are two words for the same thing = fabric or thread made from the flax plant.)

12/3 = 1mm thickness
18/3 = 0.6mm thickness
30/3 = 0.45mm thickness
