I remember having to tie my tie every morning before going to middle school. (Yes, I had to wear a tie.) Sometimes the tie would come out too short or too long. Like me, there are probably many people out there that might not know how to properly tie a tie.
I found a video that gives instructions on how to tie a tie in the following website: http://www.videojug.com/film/how-to-tie-a-tie-using-a-full-windsor-knot. The video starts by stating its purpose which is to teach the viewer how to tie a tie. The viewer knows from the beginning of the video whether the video is what they are looking for or not. The narrator also lists the materials that are needed to tie a tie. Not that there are many but none the less a materials section is a part of an instruction manual.
The steps are very clear and concise starting from buttoning the top button on the shirt to tightening the knot and putting down the collar. As the narrator says each step the person in the video acts it out. The camera gets a very close shot of the tie so as to clearly show each step to making the knot. The narrator also uses the three step phrase, "Up, Under Over," to make what is the actual shape of the knot. This phrase is easy for the viewer to remember. The video also emphasizes certain motions by saying them in a different tone and displaying them across the screen.
In addition, the video shows how to avoid the common mistake of making the tie too long or too short. It points out a seam that is on every tie that should be used as a measurement for how long to make the thinner side of the tie. At the end of the video, the tie comes right above the belt line.
At the end of the video, the narrator gives a helpful warning about removing a tie. He states that the tie should always be completely loosened because keeping it tied up in a knot might ruin the fabric. All in all this was a very helpful video for learning how to tie a tie.
