Old thread - I know but I am making some tile coasters and I stamp with Staz-On and I use just about every colouring medium SU! offers. For a lot of my tiles I have been using the Stampin' Write Markers. I bake the tiles but if I don't seal them with a sealer the coloured image will still wipe off.
Does anyone have tips or tricks for them so as not to use a sealer and negate the absorbent properties of the tile?
