I realize what you're saying....problem is, there are only 2 stores that carry any candle making supplies that I'm aware of (where I live)! Not to mention, most of the jars I've seen are very thin and not appropriate for using my "candle shade". After working all week, I find this to be relaxing and fun. Actually, until I started reading these posts, I didn't realize that re-using jars could potentially be dangerous!! :undecided
