Hi, I am having trouble with a melt and pour soap I am making for my daughter's baby shower. I am using water soluble paper w a photo on it, embedded and this last batch had a few soaps that the clear layer completely detached from the picture and the rest of the soap. I'm watching several videos and I think I sprayed with alcohol, but do I spray with alcohol right after the clear layer, then put the picture down, then spray with alcohol again?
