Looking for a quick solution to lost mittens or have some old wool sweaters lying around? Try your hand at these upcycled wool sweater mittens! I serged them quickly so they don't have the neatest outline but you could hand sew them too if you don't have a serger or don't want to mess with a serger around the thumbs which was kinda tricky (hand sewing may make this project "10 or 15 minute sweater mittens" but it's still a great quick project!).
To take them up a notch, you could line them with fleece!
