I do peppermint soaps with the snowflake mold from WSP with glitter sprinkled in the bottom before I pour and also mixed into the soap..just using a white soap base..no color. however, I think this year having my booth I will add a scent or two as well.. not sure which ones yet..but I am looking for a frosty look..so maybe a pale pale pink with pink sugar..and a pale pale green with eucalyptus..dunna yet. Love the spice idea though..since I am going to some logs and cut them with my wavy cutter that might be a thought..for the holiday spicy scents..mmm..can almost smell gingerbread
