I would tell the friend if the quilt had not been quilted. If it had already been quilted, I would not say a word....I run into this a lot when I longarm for people. If I haven't quilted it--I ask them if they want to know. If I have quilted it, I pretend like I didn't notice.....

Oh for sure I'd like to know, some times we look or work on some thing so long we do not "see" the errors. I keep all my mistakes for class samples of what not to do, hope it helps others not to do what I did. So if any of you see a opps in any of my quilts please feel free to let me in on it, with many many thanks!!

I'm with you and Alien... it depends totally on the person's attitude and intention. Quilt police can sit down and shut up. Yes, I'd very much appreciate someone's pointing it out to me before I started quilting it.
