~So simple! Layer cheap plastic beads in cake pans (no lining required), melt at 400 for 20 minutes,let cool, & then just flip them out. Drill a hole in it to make it a suncatcher! Great "craft" for kids (choose the colors, arrange them in the pans) to make as gifts for grandparents or teachers. small ones be used as coasters.. Looks like glass but not breakable!
