After pulling apart a pallet and using it to make various items I found I had a heap of left over scraps just waiting to be made into something.
The base is 12 inches long as are the internal sides. The ends are nailed into the base and are 4.5 inches long.
30 minutes job from start to finish. I used a drill and hole cutter to make holes for the rope. Once I tied the knot in the rope, I singed the ends to add a little bit more rustic feel.
