For my project, I knew I wanted to create a circular wood system. At first, I had the outer circle with 27 blocks instead of 9, and 14 in the inside circle. I laid this out on my desk and realized it would be too much drilling and less stable if I used that many pieces. I then changed the inside and outside circle so they would each have 9 so there are 18 blocks total. This ties into the length of the original piece of 2x4x18. There are two connectors on the 9 outer circle blocks and one on the 9 inner circle blocks. If I had just used one, I wold have been a lot less stable and fall apart.
