Coats Barbour 18/3
Because of its strength, linen thread is used to sew signatures in bookbinding. It is often lightly waxed with beeswax (S289).
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).
