A few months ago I made this tie for my son using THIS pattern from The Pearl Bee's blog. It was amazingly simple and looks just like a "Daddy" tie.
There are simple directions about each step on her tutorial. All of it is done by hand (so for those of you without a sewing machine yeah!!!). I found it took me a lot longer to hand sew it than I had planned on. Oh well, that's what a good movie is for right?
