Considering my hubby used to say "from one day to the next I never know what our home is going to look like when I walk in after work", I'd say I deal with changes quite well. I love changing furniture placement around, or at least I must, since I do it so often. However there are changes I don't like at all, but those have nothing to do with home, unless it's picking up and moving. I've had more than my share of that over the years and dread the thought of every moving again.
I would love to see photos of your new piece and the room too please.

I'll try to get pictures later if the sun comes out. Here's a couple pictures of "before". I'm including the second picture to show that end of the room. Please ignore the laptop, etc.
I've since changed the chandelier to a larger, more transitional piece.The new chandelier also freaked me out.

You poor dear. With all the changes that I've experienced in the last decade living in a home that is yet to be finished, you'd have gone bonkers.
I'm sorry, but I can't see your photos. The links take me to photobucket, but I'm seeing my home page for some unknown reason.

New pics:
Room with the new china cabinet

My tentative plan:
1) Take down the plates. Move the cabinet closer to the window.
2) Change the current window treatment to a London shade or valance made of this fabric:

3) I have several vintage Vera Neumann floral napkins, and I've always wanted to frame them. This one is my favorite. I'm thinking of putting this in a black frame, and hanging it on the wall between the corner cabinet and the window.

4) Cat approves of these plans. What do you think?

The dining room opens to the living room, shown here. The drapes have a very bold pattern.
Do you think the fabric I'm considering for the DR valance will work, or would you go with a solid?

Love your new furniture. Yes, I would center it on the wall after taking your plates down. The new framed napkin would be a nice bright accessory by your corner cabinet. As far as the valance......I do not think the new one or the old one do much for your room....you have a nice rug and it is figured, so I would use no valance at all or a plain colored one. I cannot see your living room images. You can probably tell I am not a valance person...I have sheers on all my windows (different colors) and not one valance. Tried valances on my kitchen window....bright red....took it down after one day and returned it to the store. Put the sheers back up.

The new cabinet is very pretty. Would it fit on the wall adjacent to where it is now? Then do plates on either side or 5 plates where the new cabinet is in the picture.

I think the London shade would be pretty, but sheers would not go with them, imo, if you want to keep the AC covered. Do you have enough fabric to make to the floor curtain panels?

Not seeing the whole room or know the size I think I'd put the new beautiful cabinet on the wall to it's right when facing it and turn the table so the end is toward the window.
I do like the idea of the London shade, but not sure about the fabric as your living room photo is not showing.

I'm having some problems with photobucket today, but will try to re-post the missing pictures.
The room has only one window, with french doors leading to an enclosed porch. It gets little natural light and is dark most of the day, so I don't want to block the window with full length drapes. The fabric I'm considering is actually an old linen/ cotton duvet cover from Anthropologie. I've always loved the pattern, but discovered that I don't like using duvets on my bed. Cutting it up will be a challenge.
Because of doors to the kitchen, porch, and living room entry, that wall is the only place for the cabinet.

I think your cat has very good taste.

How does the new cabinet look if you angle it in the corner, like the other cabinet? I have a small china cabinet angled in a corner in my DR, and it looks fine. Maybe yours is too big, though.

Beautiful cabinet. The more I look at it, the more it looks like it belongs in the room. Have you gotten accustomed to it yet?

I love your Vera Neumann napkins, but don't think a black frame would look right as you don't have any other black in the room.

That's a beautiful cabinet. I see what you mean though about it not fitting in, but that's an easy fix!

If you put some vintage pastel bowls, etc. in the cabinet it would flow with the walls, table and corner cab.

Accessorizing is the key. I'd also turn the cab around to put on the wall to the right of it.

Wow! I love your living room draperies! Have you considered carrying that pattern into the dining room? Green and purple are great together and if the rooms are open to one another, that would tie them together nicely. Did I mention that I love those draperies? ;)

As to the china cabinet, I prefer the one you had in there before. Is there any other spot you could use the new one? It could look nice in a bedroom filled with linens or books. I think its size and shape fight with the built-in you have. Your previous cabinet was enough smaller that it worked better in that spot. If the new one had a similar broken pediment or if they were both the same height and not just slightly different heights, I might like it better.

Hope you don't mind a dissenting opinion, but it is just that-an opinion, so pease don't fret over it! :)

Oh, and I love the napkin!

Love the cabinet. Love the cat. Love the Neumann florals.
Cabinet does not seem to go with the table.
