My cousin inadvertently gave me a challenge. She sent me a link to a professional dyer's page and asked if I could reproduce two colorways.
The short answer is: probably not.
The medium answer is: I've never tried.
The longer answer is: Let me Dye!
The orange/yellow/pink roving was dyed in a crockpot. The blue/green/purple was oven dyed.
Neither of them turned out like the photos I was sent....but they both look interesting to me! They both need to dry, and then they will find their way to my etsy shop (fibertwist.etsy.com).
