This is a pattern of intermediate/advanced difficulty and includes instructions for two sizes, the smaller of which should fit a head with a circumference of 20-22 inches and the larger of which should fit a head with a circumference of 22-24 inches. When designing this pattern I used approximately 150 g of medium weight yarn. Included in the pattern is an appendix with pictorial guides for some parts of the pattern which I believe may provide a challenge for some crafters, particularly those on the beginner end of the spectrum.
