In reply to Sam W:
This is funny - I asked almost the exact same question at the beginning of the year.
I ended up getting a waterproof OS map from this website centred on my house
https://www.aqua3.com/
It looks laminated but it's some special waterproof paper kind of laminate thing, my original intention was to colour in the paths I'd ran on but I didn't bother in the end, it's great just to plot routes though and look at.
I searched high and low to get it framed or get it mounted on card and it was going to end up prohibitively expensive because of how big it was, so I just stuck it to the wall instead.
Map's great though - I can highly recommend. Wife hates it though 🤣
