I'd lose sleep 3 nights running if it was me and you did tell me (this has happened once to me) BUT, I'd offer to remake it, take it back and fix it, or take a suggestion on what you'd like to do to fix the situation.
So, yeah, I'd like to know. And if it took 3 back and forth mailings before I had something you 'passed'- I'd be a far better maker for it and would probably send you another one free in thanks!
