I'm another believer in quilting problems disappearing after washing. Sometimes, yeah new issues appear but we want to know about them too. The other thing is it helps us get away from it for awhile and we can look at it with new eyes and decide whether it really is something we can live with or something we need to fix. I have taken out entire/significant amounts of work before but it is not my first choice. Still, if something is really wrong it needs fixing.
But what SallyS says is so important. It is given with love. We can love each other with the little "imperfections" that make us unique.
Final thought: if we are going to have a problem show, it's better on the back where no one should be looking anyway!
