I recognized the jar as being from a Bath & Body Works candle because I use those all the time. And I thought "why did I never think of this before!?!" (Doesn't Pinterest always do that to you?)
It was super easy. Just put the jar in the freezer. (I do mine overnight usually.)
The use a knife and tap on the wax until it breaks apart. Then it all come out super easily.
Then remove all the stickers and wash any residual wax out.
This one I used for cotton balls in the bathroom.
And another one I use as a catch-all jar in the kitchen. It had knick-knacks like my ear-buds, spare change, bobby pins, and lip gloss in it. Much better to be in a cute jar than a mess on the counter!
I'm thinking of using some to do this next Thanksgiving:
Or you could do "LOVE" for valentines day or "JOY" for Christmas. Or you could do "HOME" just for everyday.
So lesson learned: Don't throw out those used up candles! There are so many possibilities for them!
