I have to say this website is awesome! http://www.tiepedia.com/
I'm a mom of all boys so I am surrounded by ties. My husband probably owns 100 ties too. And do you think I can tie a tie? Well, I'm embarassed to admit that I can't. Neither can my sons. My boys have to ask their dad each Sunday to do their tie, or leave their tie tied so that they can just put the loop over their head.
Now I am inspired to learn to tie the ties and this website will tell me not just how to tie a tie, but to do it the fancy ways! http://www.tiepedia.com/how-to-tie-a-tie
