Right now I'm in the process of making a rag bag. I doubled the cast ons and I've been knitting it ever since. But now to the question: Is it possible for me to start the kitchenette stich to establish a bottom for my purse? And if so what would I do about the sides...could I increase the stiches and then sew up the sides?

This is so confusing....has anyone ever made a rag bag before I've tried to find info on it, but I can't find anything outside of the initial pattern!! Pics are welcome...I'm very visual!!!
