Garage storage - use a pallet! Pick one up behind a store, bolt into beams, and done! 15 minute project for organization! - finally, a project for pallets that won't bring nasty toxins inside my house.
Ok this is for a backyard wedding but I love the romantic feeling of the lights in the tree. All of my trees will have lights strung like this - maybe even from tree to tree - for ambiance on beautiful summer nights.
