A pinmoors are small plastic roll which go on the end of straight pins. I have used them with some success I have also cut my own from earplugs again they were successful. I found it quicker to use the bent safety pins than put pinmoors on so kept to quickest. I have also spray glued with good success rate. It was the elmers glue I had no success with as it created lage blobs which although it washed out the quilting wasn't as smooth as I would have liked.
