Apparently, cotton balls are more reliable than dryer lint. https://youtu.be/ClpWjEzYntg
agree with @aggieplanner , I'm loving the 'bellows' tool! I'm currently using the shaft of an old golf club.
that said, the best is when you get ALL the members of your group to go get firewood (DRY DEADFALL!) NO CUTTING! LNT! (except your campfire ring, I know, it's a little incongruous)
If it's raining or has recently rained, use birchbark and/or peel off chunks of loose bark on large oaks, etc..to get a longer lasting natural firestarter. Further, try to get twigs that are not laying on the wet ground, which make an AUDIBLE 'snap' when broken. Your Welcome!
