Borders are strips of fabric that frame the outer edges of the quilt. Whereas the binding serves to hide the raw edges of the quilt, the border may add an extra decorative finish. Although borders usually refer to the edges of the whole quilt, individual quilt blocks may have borders as well. Borders come in different styles including squared corners, which feature straight edges along the sides, top and bottom, and mitered corners, in which the corners meet at a diagonal or bias.
