I dug out another of my really old soap trays, this one only had one little crack and I was very careful not to make it worse. I wanted kind of a burgundy coloured soap so I mixed a little red liquid colour in to some purple glycerin soap. With the tray I did my usual self layering using mostly goat milk soap and then with the trees pictured below I did the defined layering. You can see the coloured soap looks darker with the defined layering.
For the Santa and Star soap I mixed the leftover coloured and goat milk soaps together for a dusty rose colour. Thanks for looking!
