This hat is an adaptation of a mitten chart that I found one afternoon on a folded up piece of computer paper, tucked inside one of my second hand knitting books. There are three mitten charts on the paper and, try as I might, I have not been able to find any further information on these charts, such as who has written them and when. If you know who has designed the charts, please email me so that I can give credit where credit is due. Thanks so much and happy knitting!
