Summarize this article in one sentence.
You can use any silverware or paper napkins you like. You can choose to use napkins that are all white, solid colored, or patterned. Just make sure they are square shaped and large enough to hold your silverware.  Make sure your paper napkins are high quality and durable. You do not want them to rip while folding. Avoid cocktail napkins that are only 9 1⁄2 inches (24 cm) square. Use lunch or dinner napkins, which are typically 10 to 12 inches (25 to 30 cm) square, and large enough to hold standard size silverware. To begin, put your napkin flat on the table. Then, place your knife on the napkin so that it lies diagonally. The point of the knife should be just slightly past the corner point, about 1⁄2 inch (1.3 cm). Where you place your knife is very important, as this how far your cutlery will stick out of the napkin roll when you’re finished. Make sure the knife doesn't stick out too far, or your silverware may fall out of the napkin. If you’re worried about your silverware roll unraveling, hold it in place with a paper napkin band. You can find napkin bands in a variety of colors online or in stores. Most are self-adhesive, so all you need to do is place it tightly around the completed napkin roll and secure it in place. If you’re using napkin rolls for a wedding or other special event, you can find some online stores that allow you to customize your napkin bands. Add your personal style to the napkin roll by tying a ribbon or string around it. You can tie the ribbon or string in a simple knot, or make a bow, depending on your personal preference. If you used a napkin band to hold the napkin in place, you can tie the string or ribbon around the center of the band.  Match your silverware display to the current season or occasion. For example, for a graduation party, wrap silverware in a white napkin and a red ribbon to look like a rolled diploma. You can place all of your rolled silverware in a basket for a nice silverware display at a buffet.

Summary:
Obtain cutlery and a square paper napkin. Place the knife on the napkin diagonally. Use a napkin band to hold the silverware in place. Tie a string or ribbon around the napkin for added decoration.
