From Sew Can She:
The finished dimensions of this tote are approximately 7'' tall (not including the handles), 8'' wide, and 6'' deep (front to back). It's a great size to carry your lunch so I'm calling it the 'Chubby Lunch Tote,' but that doesn't mean that it has to be a lunch bag. You can just as easily substitute fusible fleece for the insulated batting and use it as a small purse or zippered container.
...the pattern is Fat Quarter Friendly! Unless your fabric is directional, that is (with a print that runs up/down or left/right and you don't want to mix it up).
