Cirrus 4 Porch.
Firstly agree with the comments the porch is a nightmare to fit the first few times. When I complained to Go outdoors by email, I got the modification kit free & delivered promptly.
We used it in Cornwall last year, and the only problem we had was high winds. We did make some temporary mods ourselves.
Found that heavy duty Velcro on the overlap seam and the beam it is going on done the trick.
Personally I would have sewn the black strap into the overlap seam so you know it is pulling down correctly.
Also found it a bind that to keep it in place the guy ropes from the mod kit, we're over the side doors.
Going to try again this year in Devon shortly, but have some other ideas
