If it were mine, it would become a lap quilt, possibly with Tellabella's suggestion, maybe with an appliqued band in the join, reversing direction..
Members of my guild (except me) did bargello work a year ago. Some became jackets, others lap quilts, othersplace mats as gifts. If you have a cathedral ceiling, the single wall hanging sounds good. Whatever you decide will surely be right for you. I do hope you share it with us.
