Toy Planter Give your kid's castoff a new life in the garden. Choose toys that'll weather well and ones with dirt-friendly containers, like this Tonka metal dump truck. Another idea: Use a tricycle seat as a pedestal for a box of blooms.
Upcycle plastic containers (spray / detergent bottles) into baskets, gift bags, containers, etc. Maybe larger square gallon jugs for holding craft supplies or keeping small things together in the closet, or.
