I buy the bright colored pencil erasers from the Dollar Tree. I snip off the part of the erasers that fits over the Pencil. I use the part that is left (kinda-sorta pyramid shaped) when pinning layers together. Stick your long pins through the layers and into the flat part of the eraser. Keeps me from sticking myself with the pins as I work. I am on blood thinners and one stick from a pin results in blood on my fabric.
