Ribbon is a key component of a finished gift wrapped package. Ribbon is made in a multitude of widths, colors, designs, and materials. Some ribbon can be custom printed or hot stamped. Base materials often consist of polypropylene or other synthetic materials but may be fabricated from cotton, rayon, paper or other natural fibers. Ribbon is most often sold on spools or converted into bows or bow hanks. Bows or bow hanks will often come with an adhesive backed card attached for easy application. Bows should be complemented with the use of ribbon of the same width around the package, One exception to this is a pull bow that is constructed with an inner ribbon that can ultimately be used to attach the bow to the package and eliminate the need for a separate ribbon.
