This is another really easy project for kids. All you need are
- thin wax sheets (you get these in a craft store)
- hole punch in desired shape
All you do is punch the wax sheets so you end up with tiny shaped wax pieces. I left the thin white paper backing on the wax so it would not stick to the hole punch. If your kids are too young to do the punching just make them yourself ahead of time. Then let your kids decorate the candle with them. They just have to put them in place and press them on a little (kinda like stickers). Older kids can even cut out their own shapes from the wax sheets.
My daughter loved that activity and proudly gave the candle to her dad for Valentine's Day. I think it turned out really cute.
