So guys I need some help. The thread made for this won't let me post even if I check the stupid little box. I'm going to attempt my first dye. I have a clear cryztal challenger to work with. Below is a pic of a design I'm thinking of using. I would like to make a negative of it. (I.E. the black clear and the rest of the disc my color.) Question being is it possible to do without getting the dye on the bottom of the disc? Should I just mask off the whole bottom with painters tape? Should I just do it as a bottom dye instead? Any help would be much appreciated. Thanks Steve.
