Make old soup cans into pot holders. Tin cans are not just for stacking up in your cabinet, tossing in the trash or sending to the recycle bin. Combine those with a rope, paints, craft papers and a generous helping of crazy imagination, and you will have a cool creation on your hands.
Make a mushroom garden from little glass bud vases and plastic dollar store bowls! (can also use little thrift store/yard sale bowls!) I would put cork in the top of vase to seal it and have better glue surface.
