Start with a 8 foot 1x1. I used framing lumber since I was going for a rustic vibe. If you don’t have a mitre saw, most hardware stores will make cuts for you.
Here are the cuts you will need;
8 pieces at 6”
4 pieces at 12”
No nails are required for this project. I assembled the whole thing with only wood glue. I assembled in stages, allowing the glue to dry before I attached more pieces together.
