One of the tricky things about shades is that often the shade is the high ticket item of the lamp and shade pair. This is true even when they are new, but if bought together, the assumption is the base cost a lot more than the shade. It becomes particularly painful when trying to replace an old shade. I just replaced shades for a client that the cheapest I could find that was appropriate was $150 x 2 (delivered, they are also expensive to ship). The lamp bases were dirty and needed to be rewired so they were a relative bargain but the "total lamp" still ended up to be $200+ each, most of the money in the shade.

Tom, I think I read your correctly when you said you may not want to go in the direction of arts & crafts. First time I opened your post I saw that you have a canvas that you love and it's certainly not any definitive style but you love it and so do I so I would advise you to go for a more blended style of decor where you can use pieces from most decor styles and blend them. I find that the most interesting. Sooo I would say, keep you little end tables, they fabulous and keep your brass lamp, metals can be mixed, find a rug that's geometric with some blue in it as you'll feel so good when you see it. We can help you with all that. By the way Is that canvas Florence? Post a photo of your dining area so we can assist you to pull it all together. You'll get a ton of help from all these fine people but the bottom line is you have to love it.

The mirror is a bit too large for the buffet, IMO Have you considered hanging the mirror over the sofa and the art over the buffet? I suggest this because the wood tones in the mirror would compliment the sofa and end table. The art would bring life to the buffet and you could use the orange lamp there, as well. The new lamp for the side table…a tripod.

You can either get 2 matching lamps with smaller bases so they will work on each end table, or keep the lamp you have on the larger end table and use a floor lamp on the side of the sofa that has the smaller end table. That also would give you a larger surface to set things down on the end table. Also lower the artwork over the sofa.
