I knit this hat in one day during the Spring 2011 Squam Art Workshops. Since I had no access to the internets, I made it up as I went. Link for the pattern.
This pattern uses the same basic leaf chart as the Woodland Shawl (by Nikol Lohr) on Ravelry- except it only does the first leaf and reduces the purl stitches to 1 instead of 2. However, if you don’t want to use the leaf pattern (which actually isn’t really visible in the final product) you can use a different stitch to give it some texture. Also, don't block this.
