When using the embossing paste do you sponge color on after or mix it in to the paste? My answer, as always, it depends. It depends on what kind of color you want. Do you want really vivid, deep color or just a splash? For really deep color you want to mix some of your re-inker bottle into your paste. For a little more subtle you will want to sponge on your color with a sponge and ink pad after the paste dries.
Give it a try and see which you like better.
