Yes, but I don't consider it a problem. Currently I am working on 6 different quilts. The reason I'm working on this many is because I decided to reduce my stash all by myself and each piece I cut into has different dimensions, therefore, 6 quilts. It is going very well and I don't get bored with one quilt.
What ever I feel like working on when I start in the morning, is what I do all day. Just this week, I have one almost ready to finish. I do Quilt as you Go method. The center of this one is ready to layer and quilt. Next comes the sides, still to be pieced-no problem, I'll do that tomorrow.
