how far do i fill the cups and do i need to use papers or can o just use the crisco flour method

You can do either....are you making a cupcake cake? I always prefer to use the baking cups. You should fill them about 2/3 full.

If you're using the cupcake liners....you can get the silver foil ones....and then you don't have to even bother with the cupcake pan (I hate washing those things)...then you like like 24 of them on a cookie sheet .....helps out when you have a lot to bake and only have a 6 cup cupcake pan like me LOL
