Sweaters are a main focus for many. They use a majority of knit and crochet skills. There are tons of neat patterns out there. Sizes range from micro preemie to 5 and 6 XL. They can be matching sweaters for the whole family or all different. Holiday themes or something for the whole winter's wear is the next choice. Colors are also important to pick carefully. What looks good on one might not on the next in line. You can also use knitting graph paper and take a plain sweater and put your own graphic on it.
