I use one of those pop-up hamper thingies. But, I found a smaller one at Hobby Lobby - The base is 12" X 12" and the height is 21" tall. With the 40% off coupon it was only a few $$$. I love it. When it's all the way full, it stuffs 2 smaller sized dog beds for charity. (I found it in the front area displays by the cash registers...and it comes in different colors (mine is purple).
