I made myself a larger pin cushion last week using a bag of walnut shells that I had here for a couple years. Now I ask myself "what took me so long to do it?". I love how it turned out and the pins don't sink to the bottom of the cushion, but I did use an extra quilt block that I had left over and quilted it for the top. If using walnut shells, be sure to also use a funnel to fill with!!
