These worked very well for quilts that were either spray basted or basted with safety pins since the Grip-Its could be used over the top of the pins. However, if I was using Pinmoors, I had to remove them to make room for the Grip-Its and that was inconvenient. Overall, though, I do recommend these for a quilter’s toolbox.
LouTInstead of Pinmoors I use compressible ear plugs poked into flower head pins. Rulers and such can be laid right over them, plus they don’t have the weight of Punmoors.
