The soft, drapey Cowl neckline of this pullover reminds me of the ebb and flow of the ocean currents at Acadia National Park in Maine, which I visited when I was in high school. The greens and blues in the yarn echo the colors of the ocean and tidal pools. It has lovely curves and deep ribbing at the hips and sleeve cuffs. If substituting another yarn, make sure it's a yarn that drapes well, and that isn't stiff.
