Happy New Year!! I really don't work much in black & white so I thought I'd give it a try. All of these stitched round circles have been done with a Flower Stitch Foot. You attach the foot to your sewing machine like you would any other presser foot, pick the stitch & away you go. Most of these have been done with a zig zag stitch, however on my sewing machine, there is a heart shaped stitch which I used in the 2nd photo (in gray, up in the top left area). I'd like to try using a wash away stabilizer so the centers of these circles would be open & one could see through them.
