Easter Fun LO for Cricut class

I have been asked to teach a Cricut class at an upcoming crop in my area. I had a really hard time figuring out how to work this. I know many of you out there in the land of Cricut bloggers have held these type of classes so I'd appreciate any suggestions on how this works for you. What I came up with is to have everything pre-cut in a kit. I would provide detailed instructions on how I made all the cuts and the special Cricut features I used. Then at the crop at the beginning of the class doing a 20 minute presentation demonstrating how I made all the cuts and the features I used. Then I would let them finish their layout at their own pace. I don't think they will all be bringing their own Cricuts and probably won't have all the cartridges I used so I think time wise this would work best. Please comment with suggestions you have for this type of class. Also I was thinking of charging $15 for the class. It includes instruction and all the materials, ribbon, paper, brads, and all the tiny cuts on a strip of Xyron so they don't get lost. Would you pay that much for this?
