I've purchased those microfiber cloths which are available through Family Dollar Stores.
The package of two cloths for a buck are great for cleaning and dusting. I even use them as the "swifter" type pad.
The package of five hand towels size cloths for five bucks was useful in creating lightweight, toweling which wicked up water quickly when I was bathing our dog. Four towels sewn together with a zigzag stitch form a nice rectangle that covers the dog nicely. Two large rectangular towels do the work of the four heavy cotton towels I had dedicated to the project previously.
Now, Jones recognizes his bath towels when I am doing laundry. He loves to be bathed and brushed, part of the great care given to him by the shih tzu breeder. I towel dry the "baby" as much as he will let me and then it's time for him to "air dry" by racing around the house :D
