Product review (5 stars): Great for Quilting!
So I am using this in an unconventional way - as a slippery surface to free motion quilt.  The actual mats that are for this purpose are very expensive, $30 and up.  I decided to try this out, because it was fairly inexpensive for 3 large size mats.  It does not have the sticky back of an actual slider, but I just taped it down to my sewing table.  I marked where my needle/foot hit the mat and cut a hole easily with scissors.  The mat is working great!  My quilt is sliding freely across it, and eliminating drag (and bad stitch quality).

My husband saw the package and said "hey, we should actually try these out in our oven too!"  :)
