My perspective.
Just finished a quilt I'd been struggling with for quite some time. What a relief to have it finished. The sewing mess was really getting on my nerves while I was battling with this quilt and now suddenly I'm not concerned about the mess. It will get picked up and put away.
Also, I realize now that I kept starting other projects either in frustration or avoidance of this quilt instead of facing it head on. So for me, the issue was not the sewing room at all, it was just the result of my angst.
