this is a great way to reuse sweater's hoodies. I hated that this one was itchy and what not, so I wouldnt use it. But the hoodie is still great! I like to add this on to my layers. =]
find a old button up hoodie
cut along the buttons on both sides, and then along the hoodie. Leave a inch to sew fray edges.
sew so it wont fray. easy peasy.
