So, I had 8 oz. of a worsted-weight merino/silk blend yarn. I decided to weave it and see how it turned out.
I estimated that I had about 461 yards of yarn. Divide by 2 = 230.5 yards for warp.
I wanted a 64-inch long piece of weaving, add 20% for shrinkage and draw in = about 77 inches. 77 + 24 (loom waste) = 101 inches. That is the length of the warp.
230.5 yards = 8298 inches. That divided by twice the warp length = about 41 warp loops. (The warp would then be about 10" across.)
To center it on the reed, I threaded with 29 empty slots, 41 full slots and 30 more empty slots.
"Crank and yank" method of winding on.
Aimed for 8 ppi on an 8 epi warp.
Weaving went well and I'm happy with the result. I hand-washed it in cold water and a little Soak. The even, tight warp made weaving a breeze!
