From the pattern description: Sometimes you cannot get enough of a good thing… The idea of making a sweater to match the Swiss Cheese Socks was too tempting. The same yarn is knit at a slightly larger gauge, placing the holes every eight rows and mis-aligning them at will (let the picture inspire your placement).
