I made this bag today. I used a washable sueded fabric from the home decorating section at Joann's. The lining is from my stash - I think it's called Botanica, but don't have any of the selvedge to check.
It's very easy. I enlarged it to 110%, but next time will make it a little larger. I made the strap 24", rather than 20" the pattern called for. I also added fusible fleece to the lining and decor bond to the top section for a little more body. I'm very pleased with how it came out.
The pattern is free, here's the link:
