cute little book nook reading center for kid's bedroom or playroom - just frame favorite book covers, hang letters to spell out read, and add low shelves for kids to reach books. would like to use the ikea spice racks that are super cheap for shelving.
Make a backyard bowling alley. Add food coloring to clear plastic bottles of water. Use party streamers as lane margins. Add glow sticks for night bowling. (These would make great outdoor table nightlights also with the glowsticks, gonna try it!
