Studio Mama has taken used pallets and turned them into chairs. These would be great with a nice waterproof sealant so you can use them in the yard or the patio.
I love this wine rack. Its made from salvaged pine.
Heres a beautiful, rustic cabinet made from repurposed shipping pallets. Great idea!
Another pallet chair by Studio Mama. Check this out, you buy the instructions online to make this chair. So you can modify it with a coat of paint or waterproof it. Great for backyard BBQ parties.
