USE AS A TRAY
Clean the cookie sheet and glue on fabric. Use the decorated cookie sheet as a serving tray for food, like sandwiches or tea. Cookie sheets, decorated or plain, also make great TV trays for eating on the couch or floor. Use the more unsalvageable cookie sheets as clearing trays when cleaning up after a dinner party.
If you lack a basket or bag, use an old cookie sheet to carry things from one place to another. For example, if your kids want to color outside, put the paper and coloring utensils in the cookie sheet and carry it outside. The paper will stay clean in the cookie sheet and in place with magnets and the crayons won’t be all over the yard. Or you can carry your garden tools from the shed to the garden.
Do messy crafts on the cookie sheet for an easy cleanup afterward. Cookie sheets work great for glitter projects, finger painting, play-doh, or anything involving glue.
Use as a drip guard when cooking in the oven. For example, if you have an unsteady hand, put your pumpkin pie on the cookie sheet first before putting it in the oven. The drippy mess will be a lot easier to clean on a cookie sheet than in the oven.
Put refrigerated items on the cookie sheets. Then when you need something from the back of the refrigerator, all you need to do is pull out the sheet like a drawer instead of push everything around. The cookie sheets also make cleaning the refrigerator a lot easier.
When on a picnic, your cookie sheet can double as a serving or eating tray and a card table. Simply turn the cookie sheet upside down for a slightly raised table.
Decorate the cookie sheet with patterned paper and ribbons to use as a magnetic board (see photo). Drill a hole in one handle and hang the cookie sheet in your office or kitchen to post reminders and lists. Or make it kid friendly for your kids to use it with their magnets when you want them out of the kitchen.
Turn the cookie sheets upside down, and decorate if desired, to use as burner covers.
Paint or glue on a target to use the cookie sheet as a cheap magnetic dart board. Drill a hole in one handle to hang it up.
