littleginger73, wait for your melted MP base to cool a bit before adding very lightweight ingredients. They will distribute better. Short of that, you can pour a layer of soap, wait for it to form a thin skin, sprinkle some ingredients, trap them in another coolish layer of soap, etc. It's the ultra-careful way and you may end up with the layers showing slightly from the sides in the finished product. Just remember to spritz the ever-loving life out of each layer. And most herbs and botanicals like tea will end up turning black or brown or bleeding their color into your MP. Good luck!
