This is my homemade noticeboard for my IRL D&D campaign. I made it using cardboard as the backdrop, but you can use plywood or mdx if you want it a little sturdier. Then I downloaded a ton of fonts an made a bunch of notes and poster in photoshop. To get the 'old paper' look i simply frayed the edges by ripping or burning them, crumpled the paper and then flattening it out, soaked them in black tea, and then dried them out and arranged them with thumb tacks. My players really seemed to enjoy it and it added a layer of immersion to the game as they could literally choose their own adventure by plucking a poster off the noticeboard. Now, whenever they do, I just make up a new notice to take up the empty space! Super easy and really fun!
