This is my favorite handbag pattern: Margo by Lazy Girl Designs. I have made this so many times. The zipper can be a little tricky, but if you follow the directions closely and pay attention to the photos you will get it right. I often have overthought the zipper part, which led to much unsewing. Just follow the directions, really.
When I find a new birdie fabric, I just have to snap some up and make something. This bag is perfect! The green is very calming and zen. The white just makes me happy. And the grey with the birdie feet tracks makes me smile! It has a bright pink interior and blue pockets so you can see well inside.
