Thanks for the various comments and questions.
Bit of a delay in the update due to other hobby distractions.....
The mat with clamping points filled in:
Some more images of the mat with its Old West set-up:
Given that folding for delivery stretched the oilcloth at some of the creases, I’ve opted for rolling as my first go at storage.
It’s wrapped around a length of 40mm waste pipe and now sits on a level surface.
Rolling might flatten out the turn-ups at some of the edges, which happened when I applied the flock mix to the clamping points.
The rolled mat in the tube weighs 1.6 kg (though it’s not huge, being only 140cm by 80cm).
As to how well it will stand up to storage and use, obviously time will tell. I plan to leave it rolled for a good week or so and will then see if it lays flat and doesn’t shed grass (I’m pretty confident about the latter but have no idea about the former).
At this stage I’m about 8-9/10. I had set out to make a level mat so in that respect the odd ripple is a fail (even though at times I quite like them, that they are there when I planned for them not to be still irks ....
). The turn-ups are also a tad disappointing and without them, at this point it would be a solid 9.
