My motto is..... If it isn't quilted & you see an obvious or not so obvious error, fix the darn thing. If I could rid myself of my P (Perfect) mentality, I would have a lot more quilts done. Seriously, for me ripping out the two long sides is not the end of the world and looking at something I knew was an error would end up making me dislike the quilt. Quilts cost too much money to let something go that could be fixed.
I have realized recently that errors seem to pop out to me much more quickly if I take a picture of the quilt or block placements and look at them in a smaller version. What I didn't see when the project was life size just glare out at me on a smaller screen. Sometimes, with a scrappy, it's just too many of the same colors together. Sometimes, the blocks are absolutely turned wrong. Sometimes, I just hate the color fabric I chose for a border. Just looking through a camera has saved me time later because if I just don't like what I see in the small pic, then I am NOT going to like it. I don't want my quilts to end up as the dog bed.
Everybody can say all they want about making quilting fun & just going with the flow, calling it a designers choice, but that just doesn't work for me. Loving it with my eyes makes me feel good and want to share it with others.
