I am in the process of making some chicken pin cushions like those shown on tutorials by Jenny Doan, MSQC and Shar Jorgensen. I want to make more of a variety, but need to find a source for the walnut shells, supposedly used by lizards, I think, "Lizard Litter?". My Mom would take apart pin cushions and add her own hair to them, saying that the natural oils in the hair would keep the pins and needles from rusting.
