I made this bag from a free pattern by Lion Brand. You will need to log in to access the pattern.
Lion Brand has other, smaller versions of the same basic bag, too. Try the Golightly Tote or the Green Market Lunch Bag for a quicker, smaller project.
edit: By the way, I got the inspiration for the name of this bag from Fiona Wallice, the online psychologist as portrayed by Lisa Kudrow on Web Therapy. Click here for the hilarious episode!
