Good luck with your new sewing area. Like others have stated go as big as you can possible afford. You can never have enough room. Also when considering the placement of the electric have your plug ins above any counter top so you do not have to pull sewing tables an cabinets out to plug things in. Also have plug ins that you are going to use for your iron connected to the main light switch, so when you enter or leave the room and turn off the lights your iron will be shut off. I had mine changed, so it would do that, it was the best thing I ever did. If I forget to shut the iron off, I know that it is off when I shut the lights off. It comes on when the lights are tuned on and it gives the iron time to heat up while am getting organized to start my projects, which is also very handy. Enjoy your new room.
