I have several pin cushions but I have (sigh) lost or misplaced my very most favorite which my grandson got for me from a scout fundraiser. It was a tuna can weighted somehow and painted black with a glued on cotton top filled with fiberfill. I have sized way down so I don't want to get paint, fiberfill, etc. to make a replacement. Has anyone bought a wonderful pin cushion that handles long quilting pins and is convenient to use. Flat bottom is a must as the "tomato" I've been using gets rolypoly after I use all the pins from one side. Suggestions???
