Aproned Artist posted:I am by no means an expert on one-stroke, but I have tried it. I thin the coloring with alcohol, and I also try to keep the designs small so that I naturally use less "paint". I bought the tiniest angled brush I could find. Also, once the paint is tacky, dabbing it with a dry brush dipped in powdered sugar will seal it to some extent so that the dye doesn't rub off on the bag.
Thanks a lot!I will try with alcohol next time. I was using a medium size brush, because I have some difficulties keeping the two colors separate on the tiny one. But I guess it is all just a matter of practice
