In one sentence, describe what the following article is about:

This is a great ring size to work with, though the paper can be bigger if desired. Make sure the proportions stay the samethe paper should be twice as long as it is wide. Use a thick, colorful piece of paper for a sturdy, bright ring. Lay the piece of paper on a flat surface with the longest sides positioned horizontally. Bring the top of the piece of paper down to form a crease in the middle. Unfold the piece of paper once this is done. You're creating a hot-dog style fold in the piece of paper. With the paper unfolded and positioned horizontally again, bring the bottom long edge up to the middle fold. Flatten this section to form a crease, and then pull down the top long edge to the middle fold and form a crease here. All of the folds made so far should be parallel to one another. Without unfolding any creases, pick up the paper and turn it over so that the side facing you is smooth. Position the paper vertically and pull down the top of the paper until it reaches the bottom of the paper, forming a middle fold. Press down firmly on all of your creases. Bring each corner to the middle, creating two folded triangles that touch each other. Press down on the creases so that they're nice and flat. Only do this to the folded edge, not the opposite end where there isn't a fold. After you've formed good creases, unfold the two small triangles. Unfold the vertical fold so that the piece of paper is long and skinny, and fold in both triangles that have creases in the middle of the paper so that they disappear. After this step is done, your piece of paper will be folded in half vertically again, resembling a short pencil with a pointed tip and a flat bottom edge. The tip of the 'pencil' should be pointing left. Pull up the bottom long edge of the paper to the center, forming a crease. Do the same thing with the top long edge, folding it over so it's touching the middle. Only fold the top layer of paper, not the bottom layer at this point. Turn the paper over with the point still facing the left. Pull up the bottom long edge of the paper to the middle, creating a strong crease. Pull down the top long edge to the middle of the paper as well. Only unfold the long vertical fold so that your paper 'diamond' is in the middle of a long, skinny paper band. To make your diamond look more square, stick the flat end of a pencil inside the diamond to flatten out its top. Position the ring on your finger with the diamond facing upwards. To ensure it fits well, slide the edge of one end of the paper into the other end of the paper, tightening it as necessary. Curling the ends of the paper around a pencil can help maintain its ring shape.
Cut a piece of paper to be 5 by 10 centimetres (2.0 by 3.9in). Fold the piece of paper in half horizontally. Bring each long edge to the center fold, forming creases. Pick up the paper and turn it over before folding it in half. Fold down the corners of the new folded edge. Open the folded triangles and tuck them inside the paper. Lay the pencil-shaped paper horizontally on a flat surface. Flip the piece of paper over and fold in the other two long edges. Open the paper gently so the paper diamond is in the center. Fit the ring to your finger by connecting both ends.
