My sewing room is not large, but I had everything planned on graph paper. Probably the best thing I did was have waist high wall plugs put in -- since the house was already finished, the electrician simply put the waist high plugs higher up on the wall where the existing lower plugs were but left the original plugs in place. I also had him add extra waist high plugs where I thought I could use them (I did this through out the house). I am soooooo glad I did since getting to the lower plugs is now beyond my capability. I would have put a floor plug in but I know it would not work for me.

Thank you all for responding with many great suggestions for planning the room. I don't have pictures as the house is not built yet. But i really appreciated seeing the rooms that you have.

Lucky you!
