This video teaches you how to tie a bow tie.
Take the tie over the collar and make sure that one side is sticking a little lower than the other.
Bring the longer side over the top and through like you tie a shoe lace.
Now take the other side which was underneath and fold it into half.
Bring the high side over the top and create a little in the back in which you need to slip the high side through.
Pull it through.
Trim it up a little bit to make sure its looking good.
The bow tie is done.
