Wonderful project! Very fun. Built a bench from scrap 2x4s (left in the garage by our home's previous owner, so they were free!) and a piece of MDF shelving. Perfect for our entryway.
The bench itself was incredibly easy to build. The hard part, in my opinion, was finishing it. So many pretty things to choose from! I used a piece of 2-inch foam plus a double layer of batting for the top, some striped upholstery fabric, and 160 nailheads to finish it off. Love it.
