Know how the tie is still a pending issue for many. How many roommates I had to, even having to take daily to the office, I asked for help for this work. Of course, once they had made the knot and undid not ever.
The fact is that this problem has come to an end, at least for those that you have a tank with Apple with camera. In addition, they have developed a new application called TieSight that, using the iSight, teaches us how to tie different knots.
The process is simple: one is placed in front of the device and the camera captures your image to see ourselves as a mirror. So they appear superimposed instructions so that we can follow step by step. The nodes that are currently available are: Pratt, Windsor, Half Windsor, Four Hand, Victoria, Balthus, Plattsburgh, Cavendish, and Saint Andrew Small Knot.
Let that there is no excuse to go with the tie misplaced or to have recourse to your father that you make the knot.
