I have some lovely alpaca wool yarn, and I'm thinking about dyeing it black...but I've never used acid dyes before and I don't want to risk ruining the yarn. So what's the learning curve on dyeing yarn? How likely is a beginner to get it right the first time? I've only Kool-Aid dyed Fishersman's Wool before! (and that didn't really work very well!)
I already have some Jacquard acid dye
. So what do you more experienced at dyeing recommend? Should I go ahead and dye my alpaca yarn, or should I do a few practice runs before I try on yarn I care about?
