for me it is usually some other event that triggers a "tidying up" episode.....I have lost something and have to search for it, the end of a project that was particularly messy, and just the other day I spilled a glass of water on my computer desk (which is in my sewing room) and in cleaning that up, saw how dusty it was so wiping the dust down, the serger sits on the corner of the computer desk, that area was dusty, next to it is my 6600, everything is along the wall....you really can't dust without picking stuff up and while you have it in your hand might as well put it where it belongs........anyway, the whole thing got out of hand and I dusted the whole room with a slightly damp cloth from wiping up the spilled water.
I need a lid for my glass!!!
