How it is calculated
A 10" square sewn whole into a quilt finishes at 9 1/2". Divide the quilt width and length by 9 1/2" to get the layout.
One layer cake of 42 squares, set 6 by 7, makes a 57" × 66 1/2" throw.
Questions
Can I cut a layer cake into charm squares?
Yes. Each 10" square cuts into four 5" squares, so one layer cake equals four charm packs.
