I use them and love them. Tried the ear plugs, erasers, etc. etc. Don't think they work the same. They are stronger, tougher, and I have yet to see one of them break down. Didn't care for the quilting safety pins. Easier to pop a pinmoor onto a sharp quilting straight pin, and to pop them off during the quilting. I spray baste also-no shifting during the quilting. Makes the quilting go faster and smoother. For me, a lot less stress and frustration. Queen size quilt I use 100 pinmoors and flower pins. I now enjoy the quilting process. I did get them on sale through her site awhile ago. Along with the dedicated rulers, mats, and cutters I use, this was a worthy investment to me.
