Choose from the larger block and a Layer Cake for the main quilt -OR- a slightly smaller block and (2) charm packs instead for the slightly smaller version. I understand it it might be too hard to pick and in that case perhaps you make both...keep one and gift one?
MAIN LAYER CAKE VERSION: 62 1/2" x 62 1/2"
MINI CHARM PACK VERSION 43 1/2" x 43 1/2"
See the second picture for fabric requirements.
