Want to help out with charity knitting? The Head Start Program accepts hats that fit 3- to 4-year-old children. We recommend The Scrappy-Happy Celebration Hat pattern, available free on Ravelry. For a 3 to 4 year old, cast on 80 (instead of 96 called for in the pattern). For the remainder of the hat, follow the pattern as written. You may use a size 6 needle on the ribbing and switch to a size 7 for the rest of the hat or knit the whole hat with a size 7.
