I am about to start making a Bargello quilt for a friend. We found the pattern together and all is fine and dandy except the pattern is for a square quilt, and we need it to be longer, rectangular shape. I would have to add about 20" in length total. What do I do? Make top and bottom borders (that would look odd - right?) or fudge the pattern and extend it. I have never made a Bargello before but I fudged virtually every pattern I ever used.
