You can even make a set of unique features like this set of Pallet Adirondack Chairs:
I designed this set to have comfortable, ergonomically-curved seats and seatbacks. But, I wanted to give the set a little style, so I changed the design of the seatbacks slightly. Maybe this could be a "King & Queen" chair set? I sanded everything smooth, then applied a stain in a tone I liked.
These are comfortable, practical, and beautiful. I hope you like them!
