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

If you used sewing pins earlier, be sure to remove those first.  Once you have the wig off, use a sharp pair of scissors to cut the wig cap right along the lines that you drew. Do not cut right next to the left weft; you will be adding one more. Anchor the weft to the edge of the wig cap with a double-knot. Sew the weft to the part, this time looping the thread over the raw, cut edge. When you reach the opposite end, knot and cut the thread, then cut the weft. Choose a set of flexible wig combs that are the same length as your U-part. Sew the combs to each side of the part, with the teeth facing away from the part. Sew another set of smaller combs to the nape of the wig, with the teeth facing away from the hem.  If your wig cap has seams, line the two back combs with those seams. If your combs have stitching holes, use two stitches per hole. At this point, you can straighten or curl the wig. You can even cut it or give it some layers. A nice touch would be to razor cut the ends and the strands that frame your face. This will give the wig more texture as well as make it look more natural. It might be easier to style the wig on the Styrofoam wig head. Be sure to secure it with sewing pins or straight pins.

Summary:
Pull the wig off of the wig head and cut away the part. Sew the final weft right to the cut edge. Sew combs to the inside of the wig. Style the wig, if desired.
