I agree...it's your space..life's too short to worry about what anyone will think.
I have a sewing table set up in my living room, because that's where the tv and fireplace are!I do the majority of my quilting in the winter. In the warmer months I cut and sometimes piece a bit. I have my fabric storage and cutting table in a spare bedroom.I have an ironing board in both spaces, but the living room one I fold and put away when not in use.
I find that 99% of people love to see what's on my sewing table when they come here. The other 1% would find fault with any arrangement I had, so I pay them no mind. If it works for you, fits in your life, adds enjoyment...go for it!
