I've only got one major project (sewing, and non-urgent) going at the moment, and have been feeling a bit adrift. But there are always little things that can be done to improve a home. In my case, things like scrubbing old tape residue off doors, fishing dust elephants out from under the fridge with a stick (even with a new condenser fan, it still freezes everything...sometimes), and carefully scraping paint splotches off the woodwork.
I also moved the piano keyboard into our "school" room. It's black, and so is its stand, and they fit in better there, color-wise. Also, the radio is in there, and sometimes I like to try to play along with the broadcast music. This leaves a hole in the living room furnishings, but that spot is much brighter now without the mass of black. I am thinking of getting a chair to put there. My handmade couch is more of a daybed than a sitting couch.
