I think that many of us do that. At last count, I have 5 quilts in different stages of being done and I have one quilt waiting in the wings for me to start it. (I'll start it as soon as I have 3 of them ready to be quilted. )
I just took one off of the machine quilting frame yesterday so I will clean up my area, oil my machine and then put another top onto the frame.
