I didn???t follow a real pattern but i was somewhat inspired by the Diana, but more ???square??? and in a different size. i added an internal pocket (for mobile phone, pens and other stuff), a keyring and a colored stripe on the front just because i do love that floral fabric! :) I???m really proud of this bag even though i know i can???t sew in a straight line and it has many flaws??? ehm :)
