1. Start with the left-hand end extending an-inch-
and-a-half below the right.
2. Cross the longer end over the shorter, and pass it up through the loop around your neck. 3. Form the front part of the bow by doubling up  the shorter end. It  should measure a little longer than the distance from one collar point to the other.
4. Hold the font part of the bow between your finger and thumb, and drop the long end of the tie down over in front. 5. Pinch the place where the ends cross, and hold things together. Pull the hanging end up through the loop around your neck, and let it fall down in front. 6. Bring it around and behind the front half of the bow, then fold it and poke the folded end in through the knot, forming the back half of the bow, Even-up the ends, and snug it up against your collar.
