17' x 19'...pure heaven. I currently sew in a spare bedroom that is approx. 11' x 12' and it is getting pretty crowded.
When I lived in CO, my sewing area was in the basement and was approx. 15' x 18'. It was great to have all of that room.
Congratulations on your new home and your new sewing space. I look forward to seeing your pictures when you are all settled. Have fun setting it up.
