I made this section of fence out of the slats of eight pallets, a 10' 4"x4" treated planks, two 8' (approximate) 2"x4" treated boards and approximately 50' of 1"x1" treated boards around the perimeters and a box of #8x1 1/4" screws.
I spent a fair amount of time ripping wide boards and warped boards into the dimensions desired. The primary pattern is simply 45-degree angles, but each piece along the bottom edge is custom fit. I discovered early on that I needed to drill pilot holes before using screws. Otherwise, I risked splitting the boards.
The project took over 16 hours (digging a post hole takes time in rocky soil) but will be well worth the effort.
