I think you should persevere and complete it. I was given the same advice with my DP9P Twist and turn quilt. Everyone has such a lot of valuable experience on this board and I took heed and bordered mine and it made all the difference to the whole quilt. Having despaired, of it, hating a particular dominant beige fabric, like you, I now find it acceptable. A lot of your time has gone into that top already, and fabric, so carry on and you may be pleasantly surprised. I am still working on my borders as advised by "the wise ones" and I plan to again post when finished. Good luck.
