Mat on putting green slips.

[Frozen Rope]

Hi. I recently set up my sim and purchased the CCE 5x5 mat. It sits on top of a synthetic putting green. The problem I have is that the CCE slips on every swing and needs to be realigned after 5 to 10 shots. Does anyone have a solution that will hold the mat in place without damaging the synthetic green underneath?
Thanks

Velcro in the corners or that two sided carpet tape works very nicely for that ive found

I will give that a try. Thanks so much.
