This is a reversible pattern that lies flat. On the one side, the little pyramids point upward; on the other they point downward. The fabric is flat, firm, and shapely, requiring little or no blocking.
Only two pattern rows - Row 1 (right side): *k3, yo, double vertical decrease, yo*, repeat from * to * to end. Row 2 and every wrong side row: purl all stitches. Row 3 (right side): *yo, double vertical decrease, yo, k3*, repeat from *
