Things that turned out well:
I am really happy with the colors. The graduation in the three light colors from pale yellow to a golden tan works nicely in the corrugated ribbed band.
I love the way the circle of acorns turned out at the top of the hat.
The triangular motif that I pulled out of Alice Starmore's book sets off both the ribbing and circle of acorns. I am so glad that I did them as mirror images to each other.
Although I do like the squirrels -- the design is way too big for the hat. I am not sure I could make this any smaller for this style. Believe me I cut a lot out of the design. This is something that should go on a sweater.
The ribbing would have been better if it was narrower and done with a smaller needle. In fact the entire hat could have been done with a smaller needle.
Back to the drawing board.
