Never having tried the real Pinmoors, I can't make a comparison, but I am having great luck with a $2.00 package of foam beads I purchased at Big Lots. Yes, if I push hard enough the pin will go all the way through, but won't that also happen to Pinmoors or do they have a hard stop on one end? When I see Leah Day use hers, it doesn't seem as though she has to look for only one end to stick them in. I just FMQ a quilt using my homemade ones and it worked great. They stuck on the pins really well, but it didn't take too much of a tug to remove them. And I love the fun colours! I too didn't have much success with the erasers -- they were hard to get the pin in but slid off while I worked. These foam beads are softer but seem to grip the pin better.
