I don't have a sewing room, per se, I use most of your basement family room. The bar area is my cutting table. It's probably 36x60, I store my fabric in a 4 drawer tall chest dresser. My Janome 6600 sits in a Janome sewing table, which I purchased from Craigslist for $75. My embroidery machine sits on my DH's desk from childhood. It's drawers are filled with embroidery threads and various sewing /embroidery references.
When I want to quilt something bigger than a placemat, I move the sewing table in front of the desk so I can out feed onto the desk, then I set up a 2'x4' table to the left of both. It gives me a decent quilting table, even though all the heights are not perfect.
I have a big board for my ironing board, which I love... I take both down and stand them up against the wall in the laundry room when I'm quilting... Otherwise it feels too claustrophobic. I don't have a long arm... In order to afford a long arm, I'd also have to be able to afford an addition to the house. :-(
