How many are there?
Do you own a really good ripper?
Do you like the quilt pretty well other than the side triangles?
Do you have a good show to watch while you sit an rip of an evening?
Personally, with positive answers to these ???, I'd be ripping (or reverse sewing, as I prefer to call it).
Ultimately I'd be SO much happier with the quilt, because it it's worth doing, it's worth doing well.
