rock garden DIY Rock Cactus Garden- this if for those self declared Brown-Thumbs out there! We saw this & thought they were cute! This would be a fun project to do with the little kids, gather a few rocks on your next outing.
Bottle Bank via Martha Stewart: transform a used plastic bottle into a cute piggy bank. Could use same idea to made little containers for kids to store their collections too (use bottle with wider opening and don't make slot)
