I just finished my first hat and boy did it go fast. It helps that the cast on is only 48 sts. They request that the hats be on the small size due to newborns in under developed countries being on the small side. Also since the mail date for final contributions is January, I am hoping to get several done whenever I need a quick mindless project.
A circumference of 9" to 11" is ideal. Use any smooth, washable yarn. Any infant pattern is fine so long as it is a suitable size and will keep the baby’s head warm. Use either sport or worsted weight yarns. Scrap yarns are fine, and the patterns can be varied as desired with stripes or other color combinations.
