I just did a search to find out what "Pin-Moors" are...can you tell I am new to quilting...HA!!
I couldn't find out how big the "Pin-Moors" are....even though they are a Great idea. I wonder if you could use the erasers like the ones you buy as a replacement eraser for the mecanical pencils...depending on the size you can get 3 to 5 erasers to a package and since they come in different sizes as far as length you could cut them in half. Also wonder if the rubber backs for earrings would work?
Just some thoughts there.
Have a Great Week!!
