Here is a super fun idea I would love to take credit for. But actually, my little sister had the idea to try rub-ons on candles. They work amazingly. My tip is just to start at one end and go all the way to the other. Don't start in the middle and work out because it's a little tricky to hold the rub-on onto the candle since it has to curve. If you start on one end, you only have to hold down that part until you see the color change letting you know it's adhered to the candle. Just a note. We also tried rubbing them onto our little pumpkins. Rub-ons don't like to stick to pumpkins! So, don't waste your time or your rub-ons with that. We have plans to try painting the pumpkins or coating with a clear coat and seeing if that works. We also have plans to try rubbing them onto glasses for a Halloween party. Before I decorate all my glasses though, I want to make sure they will eventually wash off!
