Late to the party.
Here are the methods I have tried:
1. Rebatching - can be done in a crockpot or in the oven. I always am let down by rebatching as it always comes out a little too lumpy and with air pockets.
2. Confetti soap - chop up the pieces you have and add them to new batter. With those beautiful white scraps confetti soap would be really nice against a contrasting color.
3. Ciaglia soap - similar to confetti, but you stick blend the shreds in your oils to whatever size suits you - can be a very fine slurry.
4. “zero waste” bars - shred the scraps and press them into new bars by hand (as
@Lidiacgarcia suggests) or in a mold. I have a mold I made on my 3D printer for this purpose, it’s like a three piece bath bomb mold.
5. Another avenue is to do the “salting out“ method, where you add the scraps to a pot of salted water and boil it - the salt causes the soap to separate out and float on top. With your small amount of scraps it’s probably not the most efficient, but it is another way. You can find you tube videos on this method and great info here

@DeeAnna .
Lots of info on this forum on all these methods.
I have sooooo many soap trimmings right now - need to do something with them.
