In the kitchen, you can use an inverted muffin tin as a cooling rack. The space between the cups will allow the air to circulate.
If you're getting ready to decorate cookies with the kids, put your sprinkles and candies in the muffin tins to make them easily accessible and not so easy to spill.
If you're trying to carry drinnks to the table, put the cups into the muffin tin. You'll be able to carry more and you're not as likely to spill those.
If you enjoy crafts, a muffin tin is just what you need. Store different kinds of beads in each compartment for making jewelry. Or, if you enjoy painting, a muffin pan makes a great paint pallette. Squeeze your paints into the compartments and then when you need to mix colors, use one of those empty spots for swirling together that perfect shade. When you're finished painting, the tin will wash up in a snap and will be ready for your next project.
I hope you pull out your muffin tins and use them for these alternative uses. I'm Mrs. Fixit and it's just that simple.
