Not yet but I just purchased a slew of game boards (Monopoly, Scrabble and Clue) that I will be re-purposing for a variety of PnPs and my own DiY boards of other games.
I normally buy copies of Trivial Pursuit form thrift stores for a dollars and re-purpose the boards for my own prototypes. I usually print new board layouts to match the size exactly and stick them on using spray adhesive. I then use a razor to slice through the fold lines and voila! A solid, useful new board for a few bucks.
This is definitely the way that I was headed. What are your methods of printing your new board graphics? What materials? Where do you get it printed? Do you print it yourselves? Etc...
Whatever tips that you think might be useful.
