I will TRY to post a cost analysis along with the photos however, YMMV because we had some of the materials already. It was really amazing to myself and DH at how easily this thing came together! Cutting down 2 boards to an 8ft. length. 8ft x 8ft frame. 2 cattle panels, overlapped. There's our hobbit door to under our house in the background. We already had the boards and nails, so *free*. Each cattle panel was $18.99 on sale for Black Friday. So far, we're at $40!
