The center rectangle of this blanket is very simple to crochet in rounds. The outer edging complements that simplicity with an unusual shape and texture that becomes even more interesting by manipulating it around the blanket’s corners to create a frame. Instead of joining as you go or sewing on a completed edging, use the addition of a third contrast color in the pretty spike edging to simultaneously add a spark of color and texture while joining the outer edge to the center blanket.
