It's the big day, you are getting dressed and ready to go and you look at your groomsmen, you gasp and flinch at their poorly tied ties! Oh, what to do?! Learn how to tie those ties in a pinch with this awesome website I found that shows you how to tie a ton of popular knots!
There are step by step diagrams and videos that show you how to properly tie a Bow-Tie, Windsor Knot, Four in Hand Knot, Pratt Knot (Not Spencer, eew) and more! There is also etiquette advise on what knot to use and rules on length for corresponding occasions!
Above is a handy dandy example diagram of how to tie a Half Windsor Knot. The tie-a-tie website is much more helpful:)
