It is the Carmen Convertible Bag by Serendipity Studios. The pattern has two sizes you can make... Handbag (smaller bag) or the Small Tote (larger bag).
I made the smaller bag for my sister for her birthday a few weeks ago. I loved the way it turned out!
I decided to go with a linen for the outside of the bag and add a little applique flower before attaching the pocket on the bag with a little rhinestone button.
These bags are so fun and easy to make, I am actually in the middle of making the larger one for a very close friend of mine for her birthday.
