Before you begin, you'll need to decide on a shirt or sweater to use. For this project, it would be best to use a garment without a hood, but you could totally work around a hood if you wanted to get creative. Any weight, length or sleeve style will work, but there is a bit of cutting involved, so I would stay away from largely knit sweaters as they will be harder to work with. Got your shirt?
