Excellent stuff. The easiest way I've found to make them is to melt the vaseline, then drop a pile of pure cotton balls int the mix so they are completely saturated. Then using a pair of long forceps, pull a cotton ball out and put it in a garlic press and give it a squeeze. This makes a nice cotton ball that is not overly saturated.
But no matter how much vaseline you squeeze out, it will still be greasy. That's why I am also a big fan of Tinder-Quick fire tabs. These will catch a nice spark, burn well, and you can store them loosely in small kits without worry that they will get the rest of your kit items greasy. The perfect tinder for mini kits where space is tight.
