Maybe a thinner slice like this will stay on a pin better than Pinmoors. I had problems with them catching on the quilt as I was rearranging it around and they fell off, then I got stabbed with the pin. I also tried cutting up Poly-Foam backer rod, insulation, to use like the Pinmoors, but they fell off even easier. These might work fine if you aren't turning your quilt at all and have a table or the perfect set up with cabinets or tables to support a large quilt.
