Even though a lot of the time our soap doesn't come out the way we envisioned, the important thing to remember is that it's still successful because it's SOAP!
We beat ourselves up far too much!
Don't listen to your father, sorry, but you made it he can't say that!
If you absolutely can't live with it, you could grate it up with a cheese grater, then stir it through a new plain white batch at trace, it would be pink confetti soap.
What did you use to make it? Did you scent it?
