I usually do laundry once a week. But then again, its just me here! (and whatever clothes Patrick has left here). I usually do 2 or 3 over the course of each weekend. One with sheets and towels, and one or two of clothes, depending on how much is dirty. So as you can tell by my last statement, I change my sheets once a week usually. Its easy for me because I have 3 sheet sets, so I just take off the dirty and immediately grab a clean set from the linen closet. If it wasn't such a pain to try and make the bed with Marlee there, I'd probably do it more often just because nearly my favorite thing in the whole world is to slide into bed the night after I put on fresh sheets: its crisp, smells wonderful, and no wrinkles!
