I bought pressure treated plywood, used 3m adhesive spray, to attach gym mats , then fatigue mats attached same way, then artificial turf stapled for easy replacement. This is 5x4 ft, then I have another piece same way 30in x 4ft with an indent for golf balls, You can see the mat on my Instagram TYORKE1 , maybe 150 in it and well worth it, I then bought the same net as the value net from here and I have a mevo, net here friday . I have 50yrds cut in bk yard for small range
