We have several Scentsy warmers in our home. I usually dump the used wax into a jar, but when I came across this post by Jremm's outside I knew I had found a use for all the used wax.
These wafers are super simple to make. All you need is melted wax and cotton pads (the kind you find in the beauty section at Target).
I used my Scentsy warmer to rewarm the wax that had lost it's scent, but you could just as easily melt a candle or wax in a pot on the stove. Just make sure it is an old pot you don't care about, because I doubt you would ever get all the wax out of the pot.
When your wax is melted, dip one of your cotton pads into the wax.
Once your cotton pad is coated (it only takes few seconds), remove it from the wax using tweezers or another tool and place it on a piece of wax paper to cool. After the wafers are cooled you can store them in a plastic baggie, until you are ready to use them.
To start a fire, make a small tear in your wafer. This will give you some cotton fibers to catch on fire.
Once you have torn the wafer you can set it on fire, and let it burn, baby, burn.
Then sit back and enjoy the S'morey goodness.
To say I am not an outdoors person, is probably an understatement. So how these rate to other commercial fire starter items out there I have no idea, but they worked very well for what we need.
