What fun! I loved doing this stitch and love the effect! The Laced Running Stitch is an easy variation on the running stitch, but looks like you did a lot of work. It is also referred to a threaded running stitch. By lacing a second thread through the basic running stitch, you create a wavy line that is perfect for an outline or decorative stitch for both your embroidery projects or embellishing garments.
You can do it with either the same threads or different thicknesses and colors of threads. It is similar to the whipped running stitch, and can be done as a double laced running stitch. Stack rows of the the stitches close together to form a great design.
