I feel like I should be understanding this more - I have had way too many posts regarding math.
I have the Fons & Porter half and qtr square ruler. I love it and used in in my last quilt - which turned out really well. I am thinking I want to do a Jacob's ladder quilt - but again - just don't get the math. If I want a big block - lets say 18 inches finished - how does my math work out? Or would it make more sense with this ruler that I make it a different size?
Thanks so much - I don't know people quilted before this board?? :)
