Keep an eye on silk bow ties at yard sales. A lot of 18 of them recently sold on eBay for $192! I bought these for two bucks each. After coming home and doing an eBay search, I realize that I should have bought the other ten that were at the yard sale. Oops.
I only had to watch three different videos ten times each in order to ties these. I don't know how the nerds do it.
