Rip out the inside and outside seams until you get above the knee area. For straight-leg pants, mark new seams to be the same width as the leg near the knee area. For a tighter cuff, mark the cuffs to be a little thinner than the knee area and then mark new seams between your cuff marks and the knee area seams. For a boot-cut or normal cut, mark the cuffs to be a little wider than the knee area and then mark the seams between your cuff marks and the knee area seams. Finally, sew your seams along the marks. Once you are satisfied with the look, trim the extra fabric.
