Thanks for the heads up! Fortunately, my plans are mostly to revamp items by dying them black, so darkening isn't much of an issue. Do you have any suggestions as far as sealers? I have some Acrylic Resolene, as I've heard that Fiebings likes to rub off, but after applying it to the wallet, I think it might be too glossy for the purses, which were originally both matte or satiny. Is there anything that will seal in the dye, without adding much gloss?
