Pinmoors work great if you use the right pins. The thick pins (like the yellow headed quilter's pins aren't worth using with them). Everyone I know that says they don't work use the wrong pins with them. The thin sharp glass head pins work great, they go in easy and stay put. I used Pinmoors before I discovered Elmer's school glue. I noticed many of the national teachers are using basting glue in their quilts in many ways now. I use a Pinmoor whenever I use a straight pin, I detest pin pricks.
