I'm green with spice storage envy. so jealous! My spice cabinet is a nightmare! Of course we're totally demolishing our kitchen within a year or so I'll work a fix in with that remodel job.
I just made some "Money Soap" for my nieces and nephews for Christmas. I used melt & pour clear glycerin soap and embedded a gold dollar coin in the middle of each one. I finished them off with a colored bottom layer. They are lemongrass and spearmint scented. They smell really good!
I just used the melt & pour soap base that you can buy at most craft shops. I usually buy it when they have 50% coupons to make the price reasonable. You can put any kind of money in the soap even paper bills ~ the soap won't hurt them.
