I mentioned using them several months ago. I always stop and pick them up after the event is over and take them home, soak them in a bit of bleach in my sink then cut them down with a sharp utility knife. Just be sure to give them enough time to thoroughly dry out. FREE is the best price. I have not ever had any trouble with inks coming off on my fabrics, and as far as having 'politics' mixed with my fabrics, you can't see it because it's covered by my gorgeous stash! With very little effort and NO MONEY, you can have lots of boards for your fabric stash. I say GO FOR IT!!
