Here is a nice and easy way to fancy up your cupcakes for Halloween. Don't worry about decorating them when you can just dress them up.
To get started, I cut up a cupcake liner to kind of get an idea of how big it would need to be. It looks like a good 9 inches should be long enough for most cupcakes. I went a little longer and then just cut off the excess. From my experimenting I decided it was best to not have a straight liner or a circle curved liner. It seemed like an slightly curved shape works out nicely for not being too wide or too tight.
