Old cub scout doo-dah that I use for my charcoal starters and pack with me for back country survival gear is dryer lint stuffed in cardboard egg carton reservoirs and soaked with a little candlewax, enough to hold the lint together and in place. Burns quite well, is waterproof, and pretty darned cheap to produce.
Plain dryer lint won't work too good when it gets wet.
This is a variation of the cottonball/vaseline theme, but we've got the general idea here.
