Shorter on the front and larger on the back, to leave arms free without loosing protection on the neck and chest. Work it with a self striping yarn and get a great surprising result as you go. And it also comes in 5 sizes: XS, S, M, L, and XL so everyone can have their own. Available in my stores in Lovecrochet, Ravelry, Etsy, Craftsy and Allcrochetpatterns.
