This trapezoid top’s shoulder-skimming shape is created from two simple building blocks: a square at the front and a rectangle at the back. The top back curves forward to form the split-collar bodice, where it’s joined to the front with a single seam. Zippers join the side edges, allowing the piece to be worn as a poncho. Worked sideways throughout, the allover crochet wave pattern creates sleek vertical lines as it ripples the oceanic tones of Silk Garden Sock Solo #32 Pacific.
