I don't make tealigts but I ordered a few from PL (partylite) and they come in the plastic holders. I lit three in a row in my spa room. The wax had completely melted and i saw one of the wicks slide to the side and catch on fire. Lucklily I was in the room but I would not buy or make a tealight in plastic again. I have children and at work I would not chance it.
