Armed with some worsted weight yarn and a H hook, I attempted to see if I could make my most popular pattern, my Baby Hat, to fit into an adult. The only change I did was that repeat rows 6 and 7 one more time. It is still not big enough for an adult, but will fit my granddaughter nicely. In another attempt to make a larger hat I made a shelled hat. Still too small for me and now my granddaughter is getting yet another cute hat.
I have another hat in progress that should fit me. I do not have many projects that are hats, or sweaters either, because I also somehow make them too small or too big.
