srh i have done what you are talking about in a portable that had no bulletin boards. So i stapled up fabric and border to make faux boards. Its easy. I took an exacto blade/box cutter to the edges that stuck out under my border when i was done to clean up the edges a bit. Just pull it tight and start in a corner. A staple gun makes it way easier and faster, you can get one at walmart for about 5 bucks.
