This isn't anything super crafty to share, but a good idea none the less. For YW camp, part of their certification requirements is to learn about and demonstrate first aid. Me and my partner have been so busy preparing for the rest of the camp activities that we thought we would enlist the help of the local fire department to do the teaching for us.
It is a great way to learn useful information from people who do this kind of work everyday. And I will tell you, it saved us a lot of preparation and we were able to focus our efforts on other things.
