I’ve just used this product for the first time. I hate sandwiching quilts and this product made the process faster and easier. HOWEVER, I would love, love, love it if Quilters Select could find a way to color the granules, maybe like Elmer’s school glue that goes on purple and then dries clear. I had a hard time making sure that I was getting adequate coverage. Couldn't see the granules against the beige of the batting. Of course, I wouldn’t want the color to permanently show through the top or backing.
