I suppose the AccuQuilt Go Big Crazy Quilt 10" Die can be an awesome stash buster, but I did purchase my material by the yard with the finished piece in mind.

This queen sized quilt will have a black binding (on the bias which is SO easy to cut out with the AccuQuilt Fabric Cutter. (nom this is not a paid advertisement for said company :)
