Butterfly Stitch or smocking is made by making strands of yarn across the front of the fabric that are later picked up and worked together to make a gathered shape that looks a bit like a butterfly.
There are several possible ways to go about making the Butterfly Stitch, but probably the easiest is one in which the strands are worked along with a purl stitch on the wrong side of the work.
To start making the strands, knit to where your first strand should begin and bring the yarn to the front of the work.
