My first four projects: First, the crosses. I made two; the first was a bit too tall, and I didn't like how small the pad is (I haven't completed the second pad, but it'll be a detachable rectangle, about 1.5' x 2').
Schematic: (not perfect, but the key elements are 22.5 degrees on the cuts, 45 degrees between the struts, 92" long initially, cut down to 88" on the second).
