Yesterday I used normal craft moulds for pouring - but raid the kitchen for any moulds that look good - as long as they are silicone they should be fine with your UTEE. I have used lovely silicone heart cake moulds. You don't need to add a release agent, and you can really layer your UTEE, adding elements to create layers and depth. I love this technique, definitely one of my favourites. Click HERE for the links to the web site, this is some of the items I used that are on my web:
Mica flakes HERE
Graphic 45 papers HERE
The other bits and bobs were from my crafty stash - and obviously the kitchen (obviously once used for UTEE, the cake mould will never be used for cakes...not that it was!).
Use the clear UTEE, I popped a little paper in the bottom, then started to pour in the UTEE. I added words, hearts, stars, and mica flakes. You can allow one layer to cool then add another layer - this gives you depth - and a fantastic embellishment. You will get air bubbles, again pop a few, but some of them will look cool. Try it!!!
