I would love to have a separate building for my sewing, and other crafts. Someplace where if I wanted I could just leave everything out, shut the door and know no one would be dropping something off on my sewing table, or my cutting area until they were going up stairs. They always seam to forget they were stock piling there smaller items where I'm working when they do eventually head up stairs. If you do this make sure you have good heating and air conditioning, It gets really hot and dry in the summer here and really cold here during the winter (not unusual for us to have minus temps for weeks on end).
