My set up is against the wall with the window, I like to look out over the yard and watch the swallows when they are here. Then I have a short table perpendicular to that, if I'm piecing, I have a cutting mat on it to square up as I go. Ironing board has been lowered so I can sit while I press those long chains of piecing and is behind the sewing table so I have to get up and move around once in awhile.
Dad always had to be the one sitting with his back to the wall within sight distance of the door so he could assess the situation!
LOL!!! My DH, a retired State Trooper, still does this even after being retired for over 18 years. He says he doesn't want to be caught unawares if something happens. When he's not with me, I take over the door watching.
