Zeph, try buy different grass "carpets" from a company that sells artificial putting greens, like SouthWestGreens. The mat needs to be durable. Maybe they give you cut-offs for free... Screw them onto a pice of wood, but put a cushion mat (polyurethane 5mm+) underneath it.The be solution would be a 90x90cm wood tile you would use for a terrace so you can stand on it, too. You can practice in your backyard or take a small-size mat-only assembly to the range.
