They don't teach math in quilting classes any more. All is figured out for you. However, I have been doing some lecture/demos at the local quilt shop and the most asked question is how to figure yardage and make a block different sizes. After reading all the posts above.....let me tell you it doesn't take a degree or advanced study to do this. Just some simple elementary school arithmetic. If 2 plus 2 is 4 then 3 plus 3 must be six.....
The only thing that might be difficult for quilters is thinking in square inches of a color in a block and then that number in a square yard of fabric. I'm about to jump into the YTube technology and that is one of the subjects I'm working on.
