Hand Print Stones

[princesslissa.livejournal.com]

I looked in the FAQ and only found some great info about sculptures with plaster of paris. I also remember a great idea about scent stones that I have used before and love. Anyway, my question is about handprint molds. I really want to make some homemade handprint stones but really don't want to pay $15 for each kit. How does Plaster of Paris work? Is there a way to make it with flour and oils like the scent stones? I had a kit once for garden stones that I loved, but no one has gardens that I am giving thes too.

I appreciate all help that anyone can give me. Thanks in Advance!
