I had a turn dying roving with Koolaid the other day. I dyed up some Masham and some Corriedale, using the tutorial here (it is very good!).
Anyway, this is what I ended up with:
The red in the first pic is slightly redder, and the second is more green and turquoise. Camera just won't take any pics with accurate color!
They smell pretty (fruity!) and overall I am happy. You can't get much easier than dying with Koolaid in the microwave! I will check which flavors I used, and update later. Just can't remember at the moment!
