How about them eers!!!!! (People not from WV won't understand that - WV is Mountaineer territory or eers for short) WV is home to us but we have been away for quite a few years now, I LOVE your quilt, it makes me homesick.
TIP for selecting fabric: Choose one fabric that you Love/a focus fabric - then select a few other fabrics that have the same colors that are in your focus fabric. This works well and can take the headache out of selecting fabrics. For your backing, use a color from your focus fabric also.
