My #1 would be ... if I get some time, I want to be productive, not spend it cleaning!
All to prove that I can find better things to do .....
My not-so-good #2 reason ... no one sees my sewing area.
I purposely put it on the lower level, so that I could walk out and not worry about things jumping off the table, or getting out of order, and such.
Yes, it's out-of-sight-out-of-mind for me ... and visitors!
