If I can't find a single endearing quality...I say nothing at all. If its a one on one situation where I'd clearly be expected to say *something* I'd say something completely generic - "Very interesting fabric choices" or whatever. I really try to find something I like about any project, even if it's not my style. Beauty is in the eye of the beholder and I don't want to be "that guy" (well, I'm a girl) that said something about someone's work and hurt their feelings. Quilting techniques and choices are very much a personal thing. I put a fair bit of thought into the things I do for any given quilt. Maybe my color choices don't appeal to you...but there is a reason I chose them. Know what I mean? Maybe I chose those colors because they remind me of my deceased grandfather and I wanted to make something to honor him. For someone to then tell me my color choices are crap would break my heart...
