Mixed two fo's for a candy apple scent, colored with lab color red and tried to swirl with just a cupful of plain soap but unfortunatly my bottom was setting too fast again and my top was runny, someday I'll get it :embarasse . I've got to say I love this mold, right now my bars weigh a big whopping 9.2 ounces and are measuring 2 x 2.5 x 3.25. They are so nice and square and hefty I love them so much kodos to Jeff.
