i already have m ruler marked. that's not what i meant. first you make a quilt top with squares but they have to be a certain size to work with the ruler. the ruler is a 6 1/2" one. so the squares need to be slightly bigger than that. i will google around some more but if anyone her has experience making them please let me know. even if your ruler is a different size it would be helpful to know what size difference you need to make between the original squares and the ruler itself.
thanks
