The fourth outfit in my Barbie crochet collection is sweater and hat for her ice-skating adventures. Since she already has an outfit for summer, spring and fall, I wanted to add something for winter to the collection. And Barbie is now happy to have an outfit for every season. Make sure to check out all of them in my new ebook: Barbie Outfit For Every Season! Recommended yarn is fine cotton size 2. Crochet hook is 2.75 mm for sweater and 3 mm for hat. You will also need 1-inch pompom for hat. Skill level is easy.
