Pattern Notes: Piece is worked as a square, and then folded and sewn at the sides, leaving openings for the armholes. When worn, the looseness of the rib pattern tends to cause the piece to “grow” in width for a flexible fit. When measuring the length of the piece, be sure to do
so with the piece on a flat surface.

Finished Measurements: Approx 36 (38, 40, 42) inches square, before folding
