I sew in my dining room turned craft room. It is on the first floor. My iron and board are in the master bedroom on the second floor. I have often thought I really need a second iron and small board on the first floor, but have come to realize that I can piece for a while, then trot upstairs and iron. It keeps me moving! With arthritic old bones I believe it is really good for me to have to run up and down the stairs frequently. It might take a bit of extra time, but I think the trade-off of getting my muscles moving routinely while sitting at my machine is worth it.
I think I am doing my body some good, but some might think I am nuts...
