While this may look like so many fuzzy hairballs in a tube, it's actually something rather helpful. Over the past several months, I've collected empty toilet paper rolls and clods of dryer lint. Once I had enough, I stuffed the lint into the tubes, added the melted wax of three candle stubs to each, and tah-dah.
You have yourself some dandy, raging-inferno-inducing, homemade firestarters.
They work really well, and provide a steady hot flame for long enough to start a nice toasty fire. It's also a nice way to use up lint and TP rolls, somethings that are kinda hard to find a use for, in general.
