The easiest way I could do this was to video tape it. Now, I'm still learning video tutorials and didn't know my camera does this little picture when held this way...so, I'm sorry about that!
As you can see, I'm not too good at this video thing yet, so I will explain briefly what I did.
I gathered up dryer lint, used fabric softener sheets, paper egg cartons and empty toilet paper tubes. I put the wax I wanted to use on to warm while I stuffed the egg carton sections and the toilet paper tubes full of the dryer lint and fabric sheets. Then I poured melted wax over top of them till they were saturated. Let them cool and they will harden. You can cut the egg cartons into 12 smaller sections. I use about 3 or 4 sections in our fire pit each time I start a fire. These can also be tossed into a ziploc bag and taken camping. Do not use these in an indoor fireplace since you don't want any trace chemicals in your house or clogging up your chimney. If you are going to cook food on your campfire, give it plenty of time for the wax to burn off first.
You could probably make them prettier then mine if you used all white lint and pink wax or something like that....I'm not that fancy though! Enjoy your camp fire!
