It is possible to use old or abandoned shopping carts as outdoor planters, bird cages or rolling storage carts. You can also reshape shopping carts into pieces of furniture or build paper mache horse figures around their exteriors to create fun rides in which to push children around.
Placing plants in fully intact shopping carts creates a unique, quirky look for your garden. For a more conservative look, just use the main basket parts from the shopping carts, either placing them on ground level or sitting them atop poles or porch railings.
If you make shopping cart bird cages, you must create top coverings for them to prevent the birds from escaping. Keeping the wheels intact makes it easier to transport the shopping cart bird cage from room to room.
