For your quilting pleasure, we have a couple of helpful charts to offer you today. Either chart can be printed by right-clicking with your mouse and saving to your hard drive–then print. The first is a chart found by Carol Stearns.
The following yardage equivalent chart was offered by the Everyday Celebrations blog (http://everydaycelebrate.blogspot.com/2010/06/little-something-for-you.html). Other color variations of the chart are also available; use this pink version or pick a color that suits your personal sensibilties. Everyday Celebrations (http://www.everydaycelebrate.blogspot.com/) has lots of fun sewing and quilting information to explore.
