You can use our moulds with Air Dry Clay. I used clay from Artisa Soft in the UK. I kneaded in some acrylic pink paint to colour the clay and then used it with our moulds. The clay can stick to the moulds so grease the board, rolling pin and moulds well with vegetable fat. Allow to dry fully 24 hours before gluing with a hot glue gun onto a branch that has been painted white.
