Knotted Buttonhole Stitch

The fancy adaptation of buttonhole stitch creates a straight stitch with a knot at the top. It can be worked in an arc or in straight rows.

 Step 1. Come up at A, make loop with thread and hold it in position at top of stitch. Insert needle through loop at B and come up over working thread at C.

Step 2. Pull to form knot at top of stitch. Make next stitch by making loop then going down at D and up at E.
