Family Picnic is  78" x 90".  Kit includes fabric for the top and binding. Purchase the backing fabric with the kit and receive a 15% discount on the backing.
 
If you like to over-size your blocks and trim them so they are perfect, I would strongly suggest that you use a Bloc Loc ruler. For Family Picnic,  I used the 1 1/2" x 3" Bloc Loc Flying Geese ruler.
