I have some lip shaped molds I use for St Pat's Day. I do a clear M&P soap w/ a transparent green soap dye & glitter & call it "Kiss Me I'm' Irish." You can find nice fresh clover scents, etc.
I have also bought Luck-O-The Irish plastic coins & embed them in M&P soap.
What about Luck-O-The Irish Irish body mist or room freshener in a the sweet clover scent?
