How can I reuse the 3-wick glass candle jars from Bath & Body Works?

More candles? I've seen these little soy beads that you can stick a wick in the center.... or more than one.... so you don't have to make a mess with melting wax.

Set the jar in an old pot (as in one you got at a garage sale and don't mind ruining ) with a half inch or so of water in the bottom of the pot over medium heat . Watch closely . When the wax melts, pour into another prepared jar, mold, or if there isn't enough to recycle--the trash bin. Never pour into the sink or disposal . While the jar is still hot, I usually wipe out with a paper towel carefully as the jar will burn you (you'll have to hold it with a pot holder) the wax will be hot as well . Putting it in the hot water will also help you to get the label off the outside of the jar.

Here's some more ideas

Bathroom storage for small things, you can use them as decor by adding small rocks and flowers, etc.

You can make your own candles, either using the unmelted wax from the candles you have, or paraffin or soy wax and some fragrance oil. They are also good storage jars for cotton balls, etc.

This is what I got when I googled reusing candle jars. Seriously, sit down!!

paint them with glass paint and gifts are ready at all times with some fresh flowers in them.

Use it for cactus plants. They are succulents so they don't need much water and no drainage.
