Thank you this does help but the chart I was looking for gave the yardage in standard size precuts. For example x number of yards in a standard 42-squares layer cake. And it gave that information for all of the precuts. I believe it then went on to give the number of layer cakes, jelly rolls, etc. that you might need to make a baby quilt, lap quilt, etc.
I thought it came in an email but now that I think of it, it's possible that I saw it in preview pages for a quilt book on Amazon. Wish my memory was better!
