Write an article based on this "Spread out your paper and lay the folded leggings on top of it. Trace the edges of the waist, inseam, and bottom of the leg. Mark and cut out the pattern."
Take your pattern paper and spread it out on a flat work surface. Then, fold your leggings in half lengthwise and lay them out on the paper. Align the outer edge of the leggings with the edge of the paper. You will not need to trace along this edge. Use the marker to trace about along the edges of the leggings that are not aligned with the edge of your paper. Trace along the waist, inseam, and bottom of the legs. Be careful not to touch the leggings with the marker or you may stain them.  Trace about 1 inch (2.5 cm) from the bottom of the leg to allow room for the hem, 2 inches (5.1 cm) from the top of the waistband to allow room for the elastic band, and 0.5 inches (1.3 cm) from the inseam of the leg. If you want to make a slightly larger pair of leggings than the pair that you have, then trace about 1.5 inches (3.8 cm) from the edges of the leggings. Write on the paper to indicate where the inseam of the leggings will be. You may even want to draw arrows on the pattern to indicate which part of the pattern will need to line up with the fold. Then, use a sharp pair of scissors to cut along the marked areas of the pattern. This will complete your leggings pattern.
