Blueberry Muffins

Here's a cute idea I read about in a magazine ad... cut 12cm x 15 cm squares out of parchment paper to line muffin tins for muffins, cupcakes, etc. I thought it looked cool... but turns out it has a practical purpose as well. My dad has Parkinson's disease, and has troubles with his fine motor skills. It's hard for him to get a grasp of the ruffled edge of store bought wrappers. With these wrappers, there's a large corner to grab to tear the wrapper off. I imagine it would be helpful for kids as well.
It's also a good trick to have up your sleeve when you're in the middle of making cupcakes and realize you are fresh out of paper baking cups. Not that that has ever happened to me, because I am so organized!
