I just bought a pair of dye-able Coloriffics shoes off of eBay and am planning on buying a home dye kit from the Coloriffics website. Has anyone out there used one of the home dye kits? If so, what was it like? Easy or difficult to use? How were the results? Also, which color did you choose? My dress is ivory, but I don't know if I would consider it "light ivory" or "medium ivory" or "true ivory." If I can't get a perfect match, should I aim for an ivory that is lighter or darker than my dress? Thanks!
