A Bag, Anyone?

Currently I am in the process of making a fabric bag, the one labled C in the upper left on the pattern cover. I picked up this Butterick pattern during the pattern swap at the Pattern Review weekend in NYC this past May.

As I read the pattern instructions, I decided I wanted a bit more information on how to contruct a bag. So I went to my trusty computer to find information on bag making and found this great site on bag making  for newbies  by Lisa Lam. The site also give some good info on interfacing which helped me, because I am using Calico fabric that needed some support.

If you have any tips to share on bag making your ideas and suggestions are welcome.
