Tip: Don't paint a plastic tarp
Not having seen all these ideas before I created my own game board, I thought I was being smart and cost-effective by purchasing a plastic tarp at Lowe's and painting it with latex paint.
After spending several hours painting and letting it dry, I discovered that the paint will peel right off if you aren't careful.
Since I needed to use the board that Sunday, I had the children wear socks when playing which worked fine, and then I rolled up the tarp on a carpet roll. However, I'm pretty sure that the paint will start to peel off when unrolled. Therefore, i plan to salvage our board following the duct tape suggestion above unless we decide to invest in a painted canvas drop cloth, which is sure to be more durable overall.
