The finished quilt measures:
39 1/2" square - with no border as shown on the cover
48 1/2" square - with a 5" border
 
Fabric Requirements
Forty 10" squares (one Layer Cake)
Eighty 5" squares (two identical 5" Charm Packs)
Optional Border
1 1/2 yards border fabric
1/2 yard for binding
2 1/4 yards backing
 
If you would like to make the quilt larger I recommend a Fat Quarter Bundle and increase the yardage for a border, binding and backing.  The completed block is 7" square (finished 6 1/2") so the possibilites are endless!
