I don't unsew, I frog stitch. "Rip it, Rip it..."
I sew on the dining room table too. Recently we moved the Wii back to the main floor because my son was "living" in the basement. Since my LR and DR are open concept, now I can talk with him or at least supervise him while I sew. He's 10.
After a long afternoon of "Mom, watch this..", each time causing me to stop and turn around, lightening struck.
I moved the machine to the other side of the table!!
Now I can just look up and go "Ooh, aah," without missing a stitch. <3
