I purchased McCall's 2447 pattern specifically for the bow tie pattern. The pattern is listen under the men's section on McCall's website because it includes a man's vest and a tie, but obviously the tie and the bow tie can be worn by both men and women as it is adjustable.
I like making bow ties because they are fun and fast - I'm usually able to sew one up in under an hour. Also, I'm all about creative ways for using up the huge pile of scrap fabrics that I've begun to accumulate.
I haven't yet worked up the courage to sew an actual tie, but I would like to try it at least once. If and when I do, I will of course post a picture. Meanwhile, here are some pictures of various bow ties that I've made.
