Waxed thread ~ 35/3 ~ sold in 1.4m lengths
35/3 waxed linen thread in 1.4 metre lengths
"35" is a guide to the thickness of the thread, and "3" is the number of separate strands spun together to make it. 35/3 is amongst the thinnest linen threads normally available. We would recommend it for sewing any books, although larger albums might benefit from a stronger thread such as a 25/3.
Linen thread is very strong, and for most bookbinding purposes thinner threads, such as this, have more than sufficient strength. They have the advantage of causing less swell to the back of the book. This thread is waxed in the factory after manufacture.
