What to use those old metal trays for! Use them around your house as a magnet board. Put one in the kitchen ,by the front door or in your childs room. Use the board by your stove to hold recipe cards as you cook. Put import to-do-lists and important papers under a magnet by the door so you always remember what you need! Another fun thing for children learning the ABC's or learning to read, by the alphabet magnets and they can use the tin tray for practice!
