There is a method...believe it is called accent binding (sorry, I am in the family room and the information I have is downstairs and I have a cat all snuggled up in my lap. Otherwise, I would look for the information to pass on to you, smile). It is all done by machine. I just Googled "accent binding technique for quilts" and a few websites popped up. There are images for you to see. It has the look of piped binding and it is gorgeous when coordinating colors are used.
