A few days ago I added pistil stitch flowers to my garden sampler. I used Stef Francis perle 5 for the flower and perle 12 for the buds. Normally the pistil stitch is wrapped like a French knot, but I wrapped them like a colonial knot. It was easier to control the tension of the stitch. I added green long tailed woven detached chain stitches and fly stitches with perle 8 and 5.
