Somewhere I have one of those "sort of cellular looking, like a piece of corral or a dried up sponge." things. I didn't know what it was, but it's somewhere in our sewing stuff. Looks like a small 1/2" or so diameter washer made from something ivoryish in color. I'll see if I can find it.
Been sewing on the Commodore today, screwed up my bag bottoms so I might as well do something else. Don't feel like sewing any more.
