For the past two weekends, I have been working on organizing the attic and basement. Two areas that are neglected. Two areas where all the "I-don't-know-where-it-goes" or "I-don't-want-to-get-rid-of-it-yet" things go. Do you have spaces like this? I certainly do.
I came across this site and liked the concept. Each month she targets one room in her house and puts together a list of tasks for that particular room. Simple enough.
