The first step was to weigh the batt (69 grams) and spin some singles yarn trying to get close to a target size.
I want my yarn to be 8 WPI (wraps per inch) after washing. So I spun a few yards of singles at 16-18 WPI using my spinner’s control card (top right). Then I actually wrapped some of the singles. Those came out to 18 wraps in an inch. To see what freshly-spun 2-ply yarn would look like, I let some of the spun singles fold back on itself. This worked out to about 8-10 WPI on the spinner’s control card. The variation is due to inconsistencies in my spinning.
But wait, I have to see what changes will happen when washed. I measured out 2 yards of 2-ply freshly spun yarn and took it for a dip in a little warm water and mild dish soap. After soaking for a few minutes, I rinsed it in similar temperature water and hung it outside to dry.
Two yards didn’t take very long to dry. Then I brought it in, measured it on the spinner’s control card (8 WPI) and the length is now 64 inches. That means that it shrunk about 10% in the wash.
With that very little bit of sampling I learned the size of the singles I need to spin to get the size yarn I need at the finished dimensions. I’ll do the calculations for the amount of fiber I need to spin of this color for the project based on what I think I’ll need.
I’ll do same sampling for each of the other 3 colors, because the numbers might be different (different sheep, not my preparation).
Stay tuned. Let the spinning begin. Can you tell I’m looking forward to watching the Olympics while I spin?
