After spinning a good length of yarn with my light weight spindle, I unloaded my spindle onto the back of a kitchen chair then tied all four sides with short pieces of string. I then slipped it off of the chair and put it in hot tap water for 20 minutes.
I towel blotted the yarn dry and stretched it back over the chair to finish drying. This is done to set the twist of the yarn. When I took it off of the chair for the second time, it was no longer trying to unwind itself.
My first hand spun wool yarn is uneven and bumpy, but I am proud of it. Now I will spin another length of the same wool and then twist the two together to make a two-ply yarn that I can actually make something with.
