I came across this pretty cool quilting app for my iphone the other day. It makes it very easy for you to make yardage calculations for your quilts. It helps you easily calculate backing, batting and binding yardages based on your quilt size. It has other useful calculators, too like a square in a square calculator. This should help make life easier. Thanks Robert Kaufman!
BTW – I guess I blew my mom’s moon phases/labor theory out of the water because I am still here at home hanging out on bed rest.
