I never go that far without calling first, and you will have more confidence on the phone. They really should be willing to compensate you in some way for your trouble.
It would also be nice to find out, how it went, and to see how your quilt finished up.
AnnaK had a nice idea, if that works for you. Judy Martin has a book called Pieced Borders...or something close to that. I hope you are happy with the finished quilt. :D
