Take a Berenstain Bears Layer Cake or 4 Charm Packs. Divide them into 2 equal groups--one boy, one girl. If you have 10" Layer Cake Squares, cut them in 4ths, so you have 5" Squares.
Dorothy did just that. And then with LA FRANCE, just kept going around with another full round of border, then squares. The piecing actually needs 84 squares total. If your Charm Packs had 42 squares each, you are set. If cutting from Layer Cakes, you will need to come up with an additional 4 squares, from the border, binding or other scraps.
The quilts finish 54" square and are quickly ready for giving.
