After several trial runs, I found a combination of thread and stitches that gives the feel of those lush, fluffy, dusty stamens that surround the center of poppies. The black yarn is a silk and angora blend. The deep navy is DMC perle cotton. I couldn't make French knots with the fuzzy yarn but filling them in between with the embroidery floss worked very well. Next step: layering the whole piece with the batting and backing fabric and starting the machine stitching.
