I think I may have found my solution--free!!!

We're replacing the carpeting in 2 rooms at work, and the old ones are being thrown out. The one in the back room is in a few pieces, and is rubber backed carpeting--it just needs a good cleaning, and it will look as good as new!!!
Just have to ask the boss man if I can have it (can't imagine why they would say no)

Thanks for the idea!!!!!

Oh, and I'm glad to hear I'm not the only one with a room for my dogs
