Here's some fabrics I'm considering for the seat back in the eat-in area. I think I can make a backrest, possibly even tufted, if I'm understanding the DIY instructions right. So picture an L-shaped set of built-in benches, with one of these for the back. With big windows behind them, and a kitchen in blue and stainless and possibly dark soapstone. (The actual blue is a little more faded than it looks in this picture.)
I think I like the first one best.
