[milkgoddessmakesthefinestmilk]

hi, you know those paint your own piggy bank kits?
they basically come with a plaster cast piggy bank that you paint.

well do ny of you crafty gennius know how to actually make the piggy banks.
is there a way to make a mould of one then make loads more in plaster?

i want to make a few for a few family/friends babies that are due this year.

are you sure it's plaster cast and not ceramic?

moulds do need to be plaster generally. they come in 2 pieces. i had a quick look on the net but could come up with any suppliers. if there are any paint-your-own ceramic places near you phone them and see what they have available.
