I have Quilter's Select and I love it. It’s my very first ruler. I bought it about 20 years ago. I have others, but not one of them can compare to Quilter's Select. The ridges on the backside firmly grip the fabric. The quilt shop owner from whom I bought it said I would love it. And yes I do!!!
Are you sure it is Quilter's Select? That brand hasn't been available but for the last few years and it does not have ridges on the back. You may be thinking of Quilter's Rule?
