I've been on a quest recently to find out something to do with candle jar lids without dumping them into my recycle bins. So, I managed to come up with one thing for the Yankee Soy Candle wood lids.
I discovered that the wood lids can be separated from the plastic seal and used for crafts. Just use care when cutting the plastic rim.
I tossed the plastic rim into recycle and used the wood disc as the base of a wood candle holder for more stability for a future project. Using E600, I glued the wood disc to the base of the candle holder and I'll use the metal circle for another project. I had just bought a wooden disc at Hobby Lobby for $.99 but with this quick project, I got three wood discs for free just by recycling!
