Here's how to use the spelling quilt : Choose any NUMBER on the quilt. Spell it out, using the LETTERS on the quilt. You should ADD the numbers on the white squares as you spell. And you should SUBTRACT the numbers on the black squares as you spell. The result will be the chosen number you first thought of ;-)
PS: This one only works in English. Your contributions of quilts for other languages are welcome.
