I have a room just for sewing/crafting. Mostly sewing.
Doors - I am right off the family room so I'm not isolated but I can close doors if I need to.
Lighting - I have lights right over my sewing machines in the middle of the room and my cutting table is in a baywindow with lights above it too.
sewing machines - I have my sewing machine and my embroidery machine at right angles to each other so I can work on both at the same time when I want to.
ironing board - My DH made me a big one out of plywood so I don't deal with the small regular ones but I can remove it when I iron his shirts.
TV- I have a TV complete with cable.
Storage - One whole wall clear to the ceiling is solid shelves. Probably 10 ft just for fabric. I have batting up high.
Design wall - Since I am vertically challenged (short) I use the family room floor.
