Best knitting/weaving store in town, if not all of Wisconsin. Shelves of fabulous yarn in a wide variety of prices. This place takes up several rooms including a back room with a little coffee shop overlooking Monona Bay. They offer classes as well. I also recommend their Washington Island resort: http://www.thewashingtonhotel.com/
They grow the wheat for Capital Brewery's Washington Island Wheat (I think).
