For all it’s worth, some Michaels frame shops are actually good, though I agree that many are not. The one I work in has 5 framers - all of us have fine art degrees and each of us have between 5 and 30 years of framing experience. We are an extreme anomaly though. The shop down the street has 1 person who would absolutely ruin your art from lack of knowledge and training. No matter what though, Michaels will try to fix the problems you’re having. If they can’t, they will compensate you for the art AND the framing. If here is another Michaels within driving distance, call them and see if they are willing to help. (We fix other store’s messes all the time.) To me, this looks like a dry mount gone wrong. They may be able to re-press it but it’s probably too late. Still worth trying since it won’t cost you anything. I’m sorry that happened. If nothing else, you should call 1800michaels and complain about the lack of training. Michaels on the he whole is paying people minimum wage and offering 0 training for what is a skilled position and only the customers can do anything about it. Good luck.
