Hi, welcome from Nebraska! I am not one of the "normal" ones. LOL! I work on one project at a time from start to finish, except for the quilting. I was hand quilter and did get a couple of quilts behind but I am now long arm quilting them myself so I'm catching up.
The reason I don't usually start more than one thing at a time is that for one, I am much to frugal to make purchases that I may never end up using and two, it just plain stresses me out to have so much on my plate. At the moment I have several "required" quilts to make and quilt and just looking at all that I have ahead of me makes me feel almost ill. So no, one at a time for me, please!
