I think a Pringles can would be easier. They are cheap, and one could be cut in half and one could be left whole to place the sculpted part and then pour new soap in with it to make a round. The problem is the size - they are pretty big for a loaf mold.AliOop, I missed your comment about using a snap together mold - now that IS genius! And dibbles, I want to do this too... maybe a future soap challenge idea? I wonder how difficult it would be to DIY a round mold. Like, if one could split a PVC pipe, could we piece it back together for the second round pour without it leaking? Hmmm.... I must make time to play with this.... and see if Amazon carries the patience I will need to purchase to do it...
edit to add: also, how hard is it to cut a PVC pipe in half lengthwise? I couldn't do it.
