getting started, I bent a piece of scrap diamond plate between the crack of my porch steps.
Then marked it with some frame measurements and cut.
made a pattern out of cardboard and paper taped em together on the aluminum thing.
here's the mockup of the cardboard form.
it's gonna be 1/2 in ribbed on the top panel and I'll make it fit over the aluminum with a bias taped opening instead of snaps.
I'm also thinking of dropping the center edge out to the bottom seam so my legs don't sit on an upper seam. just no diamonds
like so-
hopefully I can get to sewing it up before I go on a road trip next week
