I made mine in muffin pan, I think a plate would be a great idea too ^.^ I can't wait to try different shapes and sizes..
I think I know what i am going to be doing around xmas time hehe!
I just finished it a few mins ago... I made it to go with my blue bathroom to put my ring in when I wash my face and a greenish one for my bed room night stand.
also about the smell, it is very subtle, I used cheap plastic beads from wal-mart too.
oooo also... I didn't think about doing this or know if it can be done... But while the beads are still melting can you shape to bottom with an object to fill the bottom if you couldn't get the beads to close us all the holes?
