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

Space your eyelets/grommets roughly 1 inch (2.5 cm) apart along both sides of the back of your corset, near the edge. As you reach the waist, space four pairs of eyelets more closely together by about 1/4 inch (1/2 cm). You can buy these at a local craft or sewing store.  Grommets are the holes in the back of your corset in which you lace up your corset. Use a fabric punch, leather punch, or awl to punch the holes out for your eyelets. Hammer the eyelets in place from both sides with a rubber hammer. Start at the top and lace the corset down to the waist using a crisscross pattern. Work from the bottom up in the same manner, again stopping at the waist. Tie your laces together at the waist in "bunny ear" or "tennis shoe" style.  You need about 5 yards (5 m) (4.5 m) of lacing total. Ribbon and twill are the most historically accurate forms of lacing, but flat lacing and cable cord hold up better in the long-term. The top of the corset should begin just above the nipple area, and the bottom should extend over your hips without riding up. Cinch the waist of the corset in by pulling the loops at the waist.
Insert your grommets. Lace the corset. Put the corset on.
