I just finished 12 of these little hats for underweight newborns which will be shipped to babies and mothers in need all over the world. One ounce of yarn and an hour or so per hat and you've contributed to possibly saving a life! What a wonderful service.
Wherever you choose to contribute, very well done on helping out. And very well done to your school for making it important enough to include in the curriculum for their students!
In progress - designing, knitting and writing a knitting book, "Design Your Own Gourmet
Kitchen Cloths and Accessories".
