Instead, I chose to use individual square silicone molds to create a square rimmed soap. While this can be quite a bit more laborious, the results are great. I take the slab and cut individual edges for each length and height of the mold (mine is 3" x 3" x 1 1/4"). This works for rectangular individual molds too. Each piece is mitered at the corners or you could just cut them to fit and overlap at each corner. You can even just place rimmed pieces on two opposite sides instead of using all 4. Create a new batch of soap for the inner portion and proceed as usual filling each individual mold with new soap.
Allow to gel and unmold when hardened enough to do so. These will need some cleaning and trimming to look good, but the finished soap is really unique and beautiful.

These bars were scented with a pumpkin spice fragrance that I know will turn a bit darker orange than the color shown here as the soap cures.
Not round, but still a unique rimmed soap.
Other things you can do to reclaim your failed soap rims.
- Create soap shreds to used in a new batch of soap
- Cut the rim into long strips to use as embeds
- If your slab is thick enough, use small cookie cutters to make mini guest soaps
- Create Soap curls to add to a new batch of soap
- Create soap balls to use as embeds in a new batch
Some of the above ideas have been used in these soaps below. The two soaps to the right (the embedded soap balls and flower shaped guest soaps) were from the same failed rimmed soap attempt too.
