I can sew alone if I have a project that needs to be completed ASAP. Then I sew all hours of the day and night.
Otherwise, I go to my friend's house (her stash BTW is larger than mine) and we set up the "sweat shop" there. I even have an extra machine that lives at her house! We seem to accomplish quite a lot and enjoy the time together.
PS How do you sew with the quilting board? I haven't find the audio button for that. Otherwise, I'd be right there!!!
