The cross is made up of 12" X 6" sections
Start off by cutting 34 sections at 4 1/2", 12 sections at 10 1/2" and 21 sections at 11"
It's pretty obvious where the smaller sections go. The red circled areas are the 10 1/2" sections, all remaining sections are 11" (this is due to the size between the different connectors). This will ensure that all segments of the cross are identical.
