Drawn Fabric Stitches
Barred Buttonhole Wheel
A drawn fabric stitch. Buttonhole Stitch worked in a circular motif, but rather than each stitch entering the same center hole, the circle is worked in four segments with a circular center. The cross bars are created by leaving two perpendicular threads of the fabric free. The finished wheel is only about .25" across. Best suited for fabric with a somewhat open weave.
