Mild panic yesterday afternoon when I handwashed my pinwheel blanket and blue dye bled all over the yellow and white sections. Ugh. The weird part is that the blue yarn comes from a cone I've had for, like, a year and used in other projects with not problem at all.
So, anyway, not knowing what else to do, I spot cleaned the stains, rinsed, and got most of the dye stains out. But then I started thinking that there was no way I could gift a baby blanket that wasn't washable. So, I held my breath and put the blanket through a wash cycle. This time, no blue dye stains, but a lot of blue lint which--fortunately--is not a project-ruining outcome. A spin in the dryer on low produced no additional problems.
Project details are on my Ravelry page.
