Thank you so much for all of your comments, I really appreciate you taking the time to share them!
@djfb I attached it with wood glue, it is really strong but I’m wondering if it will fail at some point, I had CA glue but I’m terrible at using it, get it everywhere, I will try that if the wood glue fails! Or maybe some epoxy.
@pubultrastar it’s faux suede with an extra layer behind I think, it kind of has a springy feel to it!
@geek2nurse I thought it might bring back wonderful memories of Japan for you!
@shogun I find they are sturdy once in place, possibly because the craft plywood has an mdf core, when I first started using this type of hinges I broke a few trying to attach them, but I found once I started getting an accurate reading for the thickness of the material it really helped the with that and they seem to be okay - I would use metal hinges for high usage though to be on the safe side
