I got this pattern forever ago from Grand Revival Design. It's the Metro Bag, and she's got a nifty thing going where you can get the pattern for free if you share her book on Facebook or Twitter. I made two (so far).
The first one (below) was my "test" version where I
just wanted to see if I could follow a pattern. I used fabric from Cosmo
Cricket's line Salt Air. My second one (above) was made with Jay McCarroll's Center City fabric. I added a snap and fun button to the bag (detailed photo at the end of the post), and it is just perfect! This is a great size bag and easy pattern to follow and quick to make.
