During the day, my half windsor tie knots tend to loosen (ie, pull away from my neck). So before running into a meeting, I'll tighten the tie up. Despite washing my hands a lot, the 2-3x a day of extra touching has resulted in a number of my printed ties getting faint stains in the same, logical place. The stains will be easy for Tiecrafters to get out, but I'd still like to hear if there's a good way to keep a tie knot in place. Thanks, guys.
