Well, I’ve just had my first (noticeable) yarn bleed experience! I had bought new yarn as blogs suggested that my stash yarn would run and the subsequent blue and white swatch washed up with no problems.
I admire multicoloured patterns /projects (e.g. Westknits bright colours) but see little mention of yarn running problems in the Ravelry notes.
So, what do others do?! Do you all prewash darker colours before knitting? Do you do anything special when blocking (e.g. Vinegar, colour catchers, synthrapol)?
I have a list of projects and brightly coloured yarns in a queue that now causes me anxiety!!
