This hat is named after "Queen of the Milliners" Caroline Reboux (1837-1927) who - in addition to her hat-related innovations - divided half her profits among the lead cashier, workroom director and other women in her employ. She is perhaps best known for inventing the felt cloche hat. See http://tinyurl.com/reboux for more info on her! Knit then felted, this pattern includes multiple variations and sizes, just right for the knitter who likes to customize. It takes less than 1 skein of yarn, too! Pattern includes instructions for provisional long tail cast on and special felt finishing techniques. Reboux went to Paris!

If it's too big, you can always send it through the wash a second time. As a general guideline or if you are not sure which to choose: for 22" or larger head circumference, use the 100 stitch cast on; 21-22" use 90 stitches; 21" or less, or for a child, use 80 stitches.
