If you are going for the longer sofa then you might consider a long narrow sofa table placed behind it that you can sit a tall lamp on to balance the window, along with a collection of framed prints or large sunburst mirror. I recommend a roman shade on the window behind the sofa even if the other windows have full length drapes. If the roman shade is made in the same fabric as the drapes they will be compatible. A plantation shutter painted the same color as the trim would also work well on this window. You may need a larger coffee table with the longer sofa especially if you eliminate side tables. You then could use a pair of small cocktail tables in front of the love seat in the bay. If you are going for comfort then add side tables next to the long sofa if the space permits. They are always more comfortable than reaching for a drink on a coffee table. A tight topped ottoman with a large tray is more useful in a living/family room than a coffee table.

Not going to answer all the questions (but I do think you should mat and frame your grandmother's lace), but I'll show you what we did with curtains/blinds in our nursery. We have a blackout shade that can pull all the way down and blocks out most of the light. It's not overly attractive, accordian style (no strings- pull down, push up), but when it's up all the way it's only like 1 1/2" thick, and it's white so it blends well. I tend to leave them half way down though. Then I made some decorative curtains that are also functional. When everything's open, it looks nice and airy, but it does a good job making the room very dark too. I used canvas, and the lining is just a sheet (cheaper than curtain liner-- $5/twin size flat sheet at Wal-mart).

I'm sorry if I'm repeating what others have said as I didn't read them all. The floor is pretty dark, but has some lighter shades highlighting it that the fireplace picks up in some of the shades of stone. Keep the brown chair with a nice camel throw over the back. Lose the busy blue chair, or recover in camel. With dark brown and camel, you'll need a large picture or area rug to show these colors intertwined with, say a red or blue to brighten the room with pops of color. I'll have to go back and read all the comments when I have more time. Good luck!

First, you are NOT going to find an exact match. These are porcelain tiles, and the shower is well on its way. Why rip it out?! All porcelain tiles have a range, even in the SAME lot. Second.....a better solution may be to keep the 20 inch for the other bath, and in THIS bath, get enough of the MOSAIC you are already using on the shower floor, and do the BATH floor in that mosaic as well. The mosaics usually present in multiple tones...use the same grout on both. The mosaic on a bath floor can look super.......and often gives a more realistic stone look to the project. It can look very rich. Mosaics are more expensive, but so is an unnecessary shower rip......and a three hour drive with tile. Put a nice white subway tile, even a large one, with the 20 inch, in the other bath. All you will then need, is a mosaic for that baths shower floor.
