I soaked some yarn a couple of nights ago, but didn't feel like dyeing last night so I decided I'd just do it this morning. It felt damp, but apparently it wasn't damp enough because it resisted the dye mightily. That was a hassle and took twice as long as it should have to work the dye in.
While I was working on the first batch, I decided to throw the rest of the undyed yarn for the dyelot into the washer to soak again. I've been doing this for several months--I can soak more yarn at a time in the washer than in a pot, and it's easy to spin it out.
... unless you get distracted. I got absorbed in dyeing and vaguely noticed the washer agitating during the soak cycle. It didn't hit me till several minutes later that, uh, you shouldn't agitate yarn unless you're interested in felting it.
I spun out the yarn and sure enough, it had started to felt. In fact, some of it had started to felt around the superwash skeins that were also in there. Grrrr. That took a while to untangle.
The yarn isn't too felted. It's definitely still knittable, so I'll dye it and offer it in my store in the future as extra-thick yarn for soakers and longies. But it certainly wasn't the smartest thing I've ever done.
I'm typing this as I eat my lunch--chips and salsa. My dyeing days are pretty low on the nutrition scale.
