This dishcloth/washcloth is based on Barbara Walker’s Double Brioche stitch (Honeycomb Brioche stitch in Nancy Marchant’s book Knitting Brioche). Whatever you call it, this stitch is one of my favorites. It is a little tricky to learn, but once the pattern becomes familiar you can fall into a great rhythm. Before attempting this pattern I would recommend familiarizing yourself with basic Brioche stitch. Making my simpler Double Brioche Dishcloth would be an excellent preparation.
