I've dryed and braided all of the roving and yarn now, and put it in the Etsy shop.
Behold my awesomeness:
I did some more dyeing on Monday night, with orange, yellow and red dyes. Unfortunately there was a bit of blue spillage (I was making one roving of orange and blue) with the result of spots of blue on the other roving. I might be able to salvage it. If not, I can either keep it all for myself or remove the blue, spin it into yarn, and sell the yarn instead. It's still drying, so we'll see what happens.
