The NY Nordic Hat is circularly-knit, with ribbing at the bottom, Norwegian-style stranded knitting motifs on the
sides and a single-colored, smoothly-shaped crown above. A nice pattern for experts and novices alike, for each
section has something interesting going on, without complications – all short floats, no weaving in necessary; never more than two colors at once; all decreases are kept within the solid-colored section. A fun knit for all!
The same set of instructions will work for knitting hats in both sizes, provided the gauge is adjusted, as indicated.
