You want to hang your Gloomhaven map without drill holes in your wall or damage your map? And you want to take it easily down and put it back up? Than thats exactly what you need!
You have to print the attached file three times and stick them to the wall according to the photos. I used 5cm long Tesa-Powerstrips to do so.
If they are mounted correctly, the map can be partially folded to put it in those to the side and than simply slided downwards into the third.
