I have 3: Fat Quarter Quilts edited by Jeanne Stauffer & Sandra Hatch from House of White Birches, Fab Quarter Small Quilts by Darlene Zimmerman and Bundles of Fun, Quilts from Fat Quarters by Karen Snyder. The Fat Quarter Small Quilts claim they can be done in a day. It depends on how many hours they consider a day (at least in my life)! It takes me that long just to decide on the fabric I want to use.
