depends on the project... and timing. I am one of the unlucky ones who have to work ha ha ha. So I have to squeeze in my quilting when I have time. The last week in June I was off work due to plant shutdown so I got to do alot of sewing

The end of the week I was kinda of losing interest and getting tired of struggling with quilting my quilt on my home machine..I did want to give up. But I knew that if I didn't finish it that week who knows when it would be finished. So I pushed through and got it done.. and I am glad that I did.
But as others have said, its nice to have a few projects in process to be able to switch back and forth when you need a break
