I haven't used wool yarn much, so I'm not sure how it behaves. I knit some practice socks (I'm learning magic loop) using 100% superwash merino yarn. Since these are practice socks, I've learned a lot and see where I can improve.
I'm now at the toe decreases, so I was thinking I would not bind off, unravel the yarn and knit the socks all over again. I've unraveled and re-used acrylic yarn before with no problems, but does wool yarn stretch out? Do I need to wet the yarn and let it dry?
