I cleared out a space in my garage. I just ordered gym mats to use as a playfield so I can tell by where I am stepping. I ordered TWO mats that are 4' X 10 ' which side by side will give me an area of 8' X 10'. I could also buy another 4 x 8 mat to add to this to make the area 8' X 14'. Should I just stick with 8 x 10 area??
