I really don't want to be a debbie downer here but I have not enjoyed too many benefits with the supreme glider mat. Too many times to count, that glider mat got stitched to my quilt! The opening in the mat is now about a 3' opening with scotch tape holding it together. The past posts suggesting taping the mat down is a great idea! I love my Martelli Rings and they do a great job of moving the quilt along. An added benefit is that I don't need to take the machinger gloves off and on. Everyone has a personal preference and you'll find yours too!
