I am in love with patchwork, and I thought it would be handy if I created some charts that had
standard quilt sizes and how many patches you need for each, as well as how many fat quarters
you would need.  I also listed a center panel column in the chart, in case you would prefer to do
a center panel in patchwork and add a border.  You can change the size of the quilt by
changing the border width.  Keep in mind, I am assuming that your fat quarters are cut
accurately at 18x22 inches and that they will have minimal shrinkage after being washed.  I also
am going on the notion that you will sew 1/4" seams.
