Learn to Sew?

Over the last few years I have given a lot of thought to starting my own company.  Originally I thought about strictly starting my own retail store, but eventually that had progressed into starting my own men's wear label.  Now I have begun to tinker with the idea of learning how to sew.  The fact that it may actually be possible for me to create something that could ultimately be sold under my banner is invigorating.... I am just not sure it is really feasible.  Let's see how this goes.
