Funny that you say that...I had to purchase a new military ball cap because the one I had was all nasty and stained looking from sweat.
I was going to spray Scotchgard on it, and realized...I don’t have any newspapers or paper bags...what could I put down under it?
And then, I had the same thought you did: What do poor birdcage owners do?
They go to a home improvement store and buy big rolls of brown contractor’s paper.
