One of the best things about sewing is being able to customize clothing to your specific style. With the Add On patterns you can create a special one of a kind outfit by mixing and matching styles over and over again. Choose from a full tank top option or 2 bib styles: rounded or square. Turn your favorite bottoms into a one piece, easy to use outfit. These work best with patterns like the shorties, ruffle shorties, play shorts, and track shorts but let your imagination go wild! Instructions will walk you through how to attach the add ons to patterns where the elastic is sewn on and then flipped over for top stitching. Check out these fun combos!
