On create and craft we have the brilliant sugar blossom shows with some great moulds. I have used these with air dry clay before - but thought lets give em a go with UTEE! Oh yeah, they work a treat. They don't need any agent to stop them sticking as they are silicone - however I did find they work better cut in half with the UTEE.
Dust the top part with mica, or mica flakes to get different finishes. To make the leaves take a piece of wire and form into an open oval. Dip into the melt pot and lift out at an angle, allowing a thin skin of UTEE to cover the oval. If you find it doesn't want to hold, and keeps popping it may be you don't have enough UTEE in your pot, or your lifting out to quick or not at an angle. Try this technique for butterfly wings.
