Thank you for helpful consumer feedback. Based on this, Mel’s Groundsheet Solutions ( not a real company) has gone back to the drawing board and is now proposing a zip in groundsheet ( such as you find on some up market trailer tents). This would be constructed of grass friendly breathable material. It would be possible to zip in before or after awning erection. Zipping in before would ensure a square awning, hence no kicking of the beams to get the thing into shape. Zipping in afterward would reduce weight. If awning manufacturers provided the zip fixings to the main canvas then a range of after market options could be developed.
The main downside would be an increase in cost to provide the zip but as many awnings cost in excess of 1k, I do not see the increase as being disproportionate.
I am awaiting the phone call from Dragons Den 😂😂
