CP137 Artificial Model Grass Mat Trains Green 40x100cm or 15.7' x 39' for Decoration Kids Craft Scenery Model DIY

Can I paint on this mat? If I can is there a recommended paint/method? Thank You

How re-usable is this? I'm thinking of using this for D&D battlemaps and will want to use it a few times each session for many sessions.

I want this for a train table, would wooden tracks lay nice and flat on this?

will it work for stop motion?
