I made a bag the other day, from some Amy Butler fat quarters.
Actually, I have been cutting squares for four of these, this is the first one finished. A tutorial for this bag can be found here.
I love the shape of this, and the bag is small, but it can still hold a lot of things. Picture number two shows a detail of the back. I quilted it with a simple stipple.
The handles are not Amy Butler fabric, I used it all for the squares! But I think this fabric works out great too, it's Kaffe Fasset, and very similar to the Amy Butler's.
