Ive seen this on several episodes and have never been able to figure out what glue or silicon they use to stick these things together to make the pretty dangly sun catcher things that they make. I recently was given some broken strands of these things by a family member of a deceased neighbor - the parent took this idea to the next level by adding some square and rectangular mirror pieces. Im kind of psyched to make some to spruce up my outdoor living area. Can anyone tell me what to use to make them stick, and also I saw one episode where they used larger pieces (about the size of silver dollars) and Id be interested in purchasing some of them to use as well.
