10-40 hours a week probably === i work on projects during breaks at work- i sew or quilt when i get home until time to fix dinner (usually allows 1-2 hours) then i sew for about an hour & 1/2 after dinner then stop to watch Jeopardy--sometimes if i'm really into what i'm working on i go back to the sewing room for another hour--sometimes i have a hand project to sit & work on while watching tv...since my day starts at 4:30am- i go to bed fairly early- but sometimes that lets me get in a bit of time in the morning too.
