I had a problem with my repair mat wherein it would slowly slide up the table. I had tried sticking it to the table with double sided tape, but the problem is the mat is very “non-stick”, nothing sticks to it. So I used two small screws to hold it to the table. Time will tell if the screws hold or not… (and yes, it *is* upside down… this is so that I can get my low component drawers out… :P)
