This is how I know I'm sick, too. I start sewing things together wrong; in the wrong order, or even inside-out so the seam is on the face of the quilt. I did that a couple years ago, very carefully pinned and sewed a whole big long border onto a heavily pieced edge...with the seam on the face of the quilt. Ripped it all out, re-pinned it to death and painstakingly sewed it back on....exactly the same wrong way. AAAHH! Definitely time to quit for the day!! I was on a deadline for that one, too.
