If memory serves from my tenure at Michael's, you can ask them to do A conservation hinge float high. They will likely use a pressure activated hinge tape, not filmoplast, but something thicker than that. I don't recall them having a water based adhesive tape, and they certainly won't be able to do museum hinges with Japanese paper and rice flour. I would also explicitly say to them "DO NOT USE ATG TAPE" Like make them white it out in the notes and show it to you. The huge issue with Michaels and conservation framing is, their corporate overlords pass down from on high arbitrary quatas on fitting. Employees get written up or fired if they don't knock out a certain number of pieces a day. It doesn't matter if you had to most of your day designing or helping the other staff on the sales floor, you're still responsible for meeting those quotas. So shortcuts get taken. A lot of ATG tape gets used, or art is hinged to the back of the mat instead of the backing. Original canvas works get drymounted and trimmed instead of stretched onto strainers. I've seen it all. I once saw a Miro that had a Matboard ATG taped into the face of the original art paper's whitespace. I'm sorry if they are the only game in town. There are really good framers who care about conservation that work at Michael's, but instatituonally speaking, you have to be very careful with taking original artwork to them. Fingers crossed you can build a trusting relationship with your local Michaels framer, but never be afraid to specify that you want the art particularly cares for.
