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. Oooh - could small ones be used as coasters? Look like glass but not breakable!
