Reader suggestion please

I will be moving into new home in two weeks. We plan to repaint the inside of the house, rip off the old carpet and polish the floor boards.

Can you suggest some way of using the carpet instead of sending them to a landfill?

At the moment, I am thinking using some of them as the base for a raised vegie bed. But I won't be able to use all the carpet for this purpose. Any other suggestion will be highly appreciated.
