Many of my knitting friends always wash their yarn before knitting, to make sure the finished object will not change in shape after knitting it.
Yesterday I placed 4 hanks in a mesh bag, the one I usually use for my bras, and popped it in the washing machine on the wool programme using a special soap for wool. Don’t use your ordinary detergent with enzymes, as the wool will get ruined.
Here they are, 4 hanks of dark grey Snældan Skipstroyggjutógv, almost dry. I will not wind them into balls until I am sure they are totally dry.
