I made this template - stapler remover used for size comparison only!
I used that template to cut out 12 wedges, I swed 6 together, and then sewed each circle to the other, right sides together. Found ti easier to leave an opening for turning & then subsequently sewing shut, on a seam between the wedges, rather than on the edge. (the curve was mor challenging to sew shut than a straight one!)
Then I stuffed them, and did some creative thread PULLING and created little flower pincushions. I have to admit, the one made of Civil War Repro's is my favorite!
