Oh yeah, I completed a 3 credit hour independent study last semester with another Fibers major. Fun fun! We went through the dye cabinet and dyed swatches in 6 depths of shade, for every color we had on hand (nearly 40, if I recall). We use Procion MX fiber-reactive dyes. I also dyed a series of mixed color swatches, and Beth did a little of the same with yarn, plus acid dye on wool. I will never see mason jars the same way. I'll post more photos of my work in the following weeks!
