1. On the 6 ft dowels, mark where the holes will be drilled.
The top hole I marked off 4 inches from the top, then every hole after that 12 inches.
2. Drill 1/2 inch holes on the markings.
3. For the 1/2 inch dowels I cut two 36 inches long and the other four 38 inches long. The shorter dowels will be used to connect the whole thing together, and the longer dowels will be used as the other sections below. If you plan to secure them all so you can’t move them you can cut them all 36 inches.
4. Space out the 6 ft dowels and insert the shorter 1/2 inch dowels in the top drilled hole. Secure them with screws. Insert the other dowels in random spots you choose. I cut them two inches longer so they don’t fall out of the drilled holes, and I didn’t secure them because I want to be able to move them when I want. If you’re never going to change it you can secure them with screws as well.
