Well, I obviously don't know how to search properly on Etsy because I'm not finding any cushion covers that would work in your space. They do offer an alphabetic list of fabric options though and the ones that I would consider for texture and a glam touch are: cashmere, faux fur, fur, satin, silk (including dupioni), suede, velour and velvet (incl. crushed). That doesn't mean the whole pillow needs to be in any of these fabrics; if you're going the custom route again, perhaps these could be trim on linen pillows. What I'd want to consider when adding pillows is balancing the colours and textures in the room. If you have a lot of shine already, you don't want all the pillows to be super shiny, etc. I saw this crushed velvet cover and wondered how that type of fabric would look on your print chairs. Echo a bit of the adjoining leather's shine without being all shine? Super soft fabric that gives a cozy vibe as well. Here are trimmed pillows that reminded me you can certainly use just a touch of these fabrics for that glam touch. I've no doubt you can find better options out there!

This is a duplicate post. can you keep everything to just one of them? https://www.houzz.com/discussions/6031063/help-i-need-ideas-on-how-to-finish-decorating-my-living-room#26272579

Curtains would be a good idea. Even though you have blinds for privacy, curtains make the windows look finished. A little eyeliner besides the mascara. I would not do a colored curtain here. Curtains are just to darn expensive to have to switch out when your color palette changes. I would suggest white or off white, whichever you prefer in a silk or silk-like fabric, and get a marvelous trim for the edge. The edge trim can be in a white and black or whatever color you want to take from your rug or elsewhere in the room. I would not do a curtain trim in gold here because I see 4 windows, for 8 panels, that would be a lot of gold. You want tasteful gold embellishment in a space, not Liberace in Las Vegas. Here are some examples of trimmed curtains. Buy the plain curtain, and then buy the trim of your choice, and buy extra trim to embellish throw pillows, and buy coordinating different scale trim for other throw pillows. Another curtain option is a white curtain with a subtle pattern woven or printed on it.

Thank you Louis. The agreeable gray walls are really more a beige and it is temporary. I am looking for a wallpaper above the wainscoting that will be installed next week---something with blue even if just grass paper (I think that is what is called). I just need to decide mirror and lighting for now because that will be what my contractor wants next.
