wow, you have 4 sewing machines in your sewing room?!
Mine is small so only one, but even so (sew) we manage to collect portables. At one time we had over a dozen, most we got free.
In my previous house (9 room colonial) I had a nice big sewing room that didn't have to double as anything else. I miss it sometimes. Now we are in a 4 room ranch w/cellar, things are a bit tight. I have to move the kitchen table if I need to baste a quilt.
