Cute! Glad you found something to use!
(princessketu, the olive oil doesn't make liquid clay, it's a substitute for it. Various oily materials will work to thin solid polymer clay--e.g., veg. oils, mineral oils, Softener-Diluent, glycerine, Vaseline, softer polymer clays, as well as liquid polymer clays, etc.)
Vaseline?! Wow I used glue once but it just dried.... silly me. : D These are so cute!
