First of all, all I can say is WOW! the Quilt is gorgeous and the border will be fantastic on it.
In all the years I have been quilting, it is never too late to learn something. I had never heard of the term "cope" as far as quilting is concerned. Now I have. Makes perfect sense. I have done it many time - who knew there was a term for it!
Can not wait to see the finished quilt.
