Unlike you, weekends are the only time I get sewing done. That means I must organize myself, including my mind, to be in a sewing mode.
It helps the most when DH does the housecleaning for me on Friday. If he doesn't, I do it first and then sew. Laundry happens during sewing time and folding provides little movement breaks for me. If there's really a lot of other stuff to do, I try to get it all done on Saturday so I can spend Sunday at the machine.
It's very annoying when we have weekends like my last one, where we go into town and end up spending two nights there. So sad, weekend is gone by the time I get home.
