Too many to count! I just cut out 3 more today. I finished 2 baby quilts and a quilt top the other day. I've got a couple that need to be quilted, another that needs borders added, plus some that I've already kitted up and a few that I pulled fabric aside, but have yet to do anything with. Another that I cut wrong and had to rip out and reconfigure. I finally got it ripped out yesterday.
Most of the time I have to dismantle my quilting area when I am thru, so I keep piecing when I can (I have a very tiny area to work in my bedroom) and quilt when I can set up without having to take down in a few hours. Assembly line works best for me, even if it means working on multiple projects.
