Follow the layout and sew the star block together.
Cut a 6-7″ piece of batting and center the star block. Sew log cabin strips which are cut 3/4″ wide in a courthouse steps pattern around the star, 4 or 5 rounds, depending on how big you want the pincushion to be. Reduce your stitch length.
Zig zag stitch around the final row and trim away the batting. Lay face down on a 5-6″ piece of backing (I like velveteen) and stitch around the “pillow” leaving an opening to turn. Make sure your stitch length is reduced.
I fill pincushions with a mixture of play sand and sawdust. If I have lavender, I like to add some just because it smells so good. Fill it very full and plug the hole with a bit of batting or fiberfill to keep the sand from leaking out. Sometimes I’ve even made another little filler pillow to put the sand in but it’s just another step and more work. Reducing your stitch length will keep the sand from leaking out. Close the opening very tightly by hand. No, I’ve never used crushed walnut shells but you could. There is only one thing you cannot use to fill a pincushion and that is fiberfill. Your pins won’t go in, it’s not heavy so it will fall off the table, and pins that do go in will rust – it’s just a bad idea. If you’re just wanting to make a sweet little pillow, go ahead and fill it with fiberfill because it doesn’t have to function.
