I use dryer lint since I do the majority of the laundry. I keep it in a Ziploc bag. It's light as a feather and works great.
This is a good way to ration out portions of fine steel wool for ez fire starters, too. Eliminates having to shred off a tuft in the dark, and always provides the right amount for a fire. Steel wool has the advantage of providing a very hot starting flame from even the smallest spark. It's also essentially weightless.
I just can't get past cotton balls with vaseline. It just works and is so easy to make a hundred of them.
My wife used to make them from melted candles purchased after Christmas, mixed with dryer lint with a popsicle stick stuck in the center.
go out to the woods that have pines in them and find an old pine log that has rotted down to the hard centre that is what you want just shave a few pieces and light them--hot fire from all that dried sap
