“Clover is worked in one piece beginning at the lower back edge. Most shaping is accomplished by changing needle sizes. It’s finished with a crochet picot edge, and an optional buttonhole can be worked at each side to close.
The original was knit in cotton, but it’s nice in wool, too. Keep in mind if using wool, it has more elasticity than cotton, so it may be necessary to knit one size larger than you usually would.
