I ordered some Cova Color paints from Tandy's and got a sea sponge. Heres what I've managed on one of the small journals I do. Not a very good photo taker but it looks pretty good to me.

Hay everyone, I've been eyeing another leather workers art for some time and wished I could do something like it. You can check out their work here: http://www.lescuirsdebelfeuil.com/en-photos.html . My question is about the vibrancy of the colors they use, especially the greens, blues, and purples. I've tried plenty eco-flo dyes but they always turn out washed out or too dark by comparison. So would this be paint they are using or some other dye brand I dont know of? The kind of marbled/flame like effects would be nice to know how to do as well but one step at a time.
