Alf..How LinienThread Sizes are calculated.

No.1 yarn is 1 pound of flax spun to a length of 300 yards.
No.2 yarn is 1 pound of flax spun to a length of 600 yards.
And thus;
No.18 yarn is 1 pound of flax spun to a length of 5,400 yards. (300 x 18 = 5,400)

Taking for example a "18/3" thread.

The "3" refers to the number of yarns that have been plied together.
The "18" indicates that it takes 5,400 yards of such yarn to weigh a pound.

It can be seen why bigger numbers mean smaller thread -- the thinner the yarns, the more of them it takes to make a pound.

To conclude.
A 35/3 thread is made of three yarns, each made from 1 pound of flax spun out to 10,500 yards and then twisted together.



Are you trying to repair a holster?

By my calculations I would guess you would want a #18/3 or a #18/4 strand depending on what holster you are wanting to restore.

Hope this helps...
