Overcast symbolizes a stitching technique that involves creating
small in and out stitches to tightly join two fabric pieces together. This method provides durability and prevents the material from fraying. The join together may be used for a selection of stitching projects, such as sewing the hem, sewing patches, or even making coverlets. It offers a clean and skilled look for the final product.
