I make a lot of glycerin soap and have wondered about using the foam in soap. I figured it would float so was reluctant to try it. Your glue method is perfect and so simple! Yay!

Thanks for the inspiration! :)

I am not sure whether a photo or something on cardstock would hold up, to be honest. I’ve not tried! I chose the foam because I thought it would be sturdier than paper, but perhaps cardstock weight would be ok? You could always just give it a try and see what happens – the supplies are fairly inexpensive and provide more than enough to make many bars of soap. It could be turned into a fun experiment with the boys! And if the cardstock doesn’t seem to hold up, ask their input on what to try next. Small toys should work, as should pre-cut foam shapes they might find at the craft section. Good luck!
