The exterior fabric is a very thick kind of upholstery fabric that my great-aunt gave to me. For the lining, I used a cotton I inherited from my grandma that has vintage cars printed on it.
It's a great weekend bag. It is very, very large and will carry everything you need for the entire day. I made a few modifications on the straps and binding. Because I didn't have quite enough fabric, I cut the straps and binding on the grain instead of the bias. Then, when I applying them to the bag, I only folded the strap once lengthwise and sewed it to the bag. My fabric was very thick so I thought it would be simpler my way. It worked out fine and I'm very happy with the finished product. I highly recommend the pattern and will probably make it again.
