I use Fiebings dyes, which ones depends on where I get it. Hobby Lobby only has low voc (?), sometimes I can get the regular stuff, but haven't tried the oil dyes. As far as dyeing, I have recently taken to diluting it about 50/50 with water, and dip dyeing in a big ziplock bag. I call it the "Shake and Bake" method, and I seem to get better color tone and coverage.
