I am currently knitting teeny hats for the East African Preterm Birth Initiative.
These little honeys ares pure stash-busting, potato-chip knitting for a good cause. I am using the worsted weight pattern at the linked site, but there are sport weight and crochet versions, too; or you can use your own favorite preemie hat pattern. Address to send the hats is at the linked site. Deadline is November 5.
