This simple tissu with green motifs. I more or less plan to build a textured surface from a tissu, with a flexible glue, but i still have to do it.

You could glue a ring of static grass around the tent base so that it matches the table (assuming you have an all-grassy table), then just glue patches of grass (like the current one) on the rest of the base. That way you'd still have some clear areas of ground to see your painting efforts, and by where and how thick you make the grass you could add to the story of the scene.
Even if i don't have the static grass table, i'm on this idea for now. Not because of the painting job i did on the ground, wich is really basic, but for the general aspect. A complete static grass surface cancel any other work done on ground.
For example, it may be good to leave a ring of clear dirt around the tent, showing the damage done to the grass when the tent was first set up. Additionally, I'd expect guards to patrol around the tents sometimes- they'd have warn a path.
More precisely, and considering the tent is not here for a long time, i think grass is still here just at the tissu level. Nobody walk just along the tent, because of the shrouds. And mounting this type of tent is not that long too. So i don't think people will have trampled every piece of grass just in the direct area.
About guards walking around, you're right. They would have done a complete path with no grass, or at least trampled grass, wich is the same for us.
Around the horses there should be varied grass within range of a rope + horse length. Anywhere the horse could get its head to would be completely grass free (they eat a lot), the rest of the area would be light to no grass, due to trampling.
Completly agreed.
If you do go with the grass trimming idea I'd suggest you save your fingers and get an electronic shaver- set it very low, then shave your grass. Just give it a very good rinse afterwards if you intend to use it on your face...
I plan to see if i can find a nose hairs shaver. They are thin enough to do more or less what i want i hoper. I'm balancing between taking time to test all that and continuing next week end.
It's actually that I whisper my ideas to you while you sleep...
It was you who waked me up that night at 3 am shouting "daaaaaady" ?! I thought it was my youngest daughter

Reminded me of something I saw a while ago, electrostatic flocking... Have you come across or used that before?
I had heard about that technic, but never saw it. Interesting link, thanks a lot.
I'm not sure it solves my problem but it could help... If i can find this shaver.
