I have some commercially made ones that I do use to cover bowls and occasionally to wrap things. Because they aren't clear, it hard to know what's inside them, but they do work just fine. They stay where folded and mold to the item due to the warmth of your hands. I haven't tried to make them, however. Seems like a lot of messy work what with the wax. Reminds me of the candle making days of the 1970s!
