Are you going to open those up a bit to allow room for fabric? Or do you have way to mount that doesn't involve the fabric wrapping around the plywood?

We got flagged at MSC last year for dadoing all the way top to bottom on our bumpers, it might be worthwhile to think about a reinforcement at the top. We only went through 1 ply maybe 1.5 too. Our plan for this year was to just dado up far enough for the bolt heads to fit, but then we just made them bigger instead.
