I, too, use very few paper towels. I'm pretty sure that I've been working on the same roll of paper towels for at least the last month, and I've only gone through half of it.
I did go through a period when Seren was a puppy and working on house breaking that I went through a bunch, but now that we're done with that in general I use cloth rags, towels, and sponges.
I do like paper towels for cleaning windows, especially my car windows, as they do a superior job at removing streaks and smudges.
