Back in May, I had to make 30 bow ties for the Italian Contemporary Film Festival. Though I had made a tie before, I had to find an easy enough patter to 'mass produce' these bow ties.
The tutorial from Sew Like My Mom perfectly guides you through the steps to making one.
I finally got to make a bow tie for me. The only alteration is that I made to the pattern is that I shortened the neck length to fit my small neck (12 inches). I also watched and looked at many tutorials to figure how to tie it.
