Do they need anything else, if the wall space is appropriately chosen (and can’t tell their size either). Can you show the wall they will be hung, to give some perspective. When you say decor, do you mean on a piece of furniture underneath?

It will go right above the sectional. Wall color is a very light blue/Grey

I was thinking more of what other wall decor would go with it. But would also be curious as to what color throw pillows

Matthew - I think the beautiful workmanship will get lost on that wall. I suggest finding another spot where you can come up close and look at these. Not the same thing, but similarly, I have antique maps which would fill the space, but can’t be appreciated for the detailed beauty. I hang only one or two in a spot where they can be better seen.

What other wall decor would you suggest to fill that wall above the sectional?

I would hang those in a bedroom or hallway.

Your mother wants you to hang them in your house? Sounds like this goes beyond decorating advice ...

No. She wants me to hang it in her house.

Place them instead on a small wall vertically and they will stand out and be more appreciated.

Use more proportional art over sectional and duplicate its colors in the cushions. Ask your mom what she likes subject wise (florals, landscapes, etc). Color combo below would be complementary.

What color art do you think would look good? Wall is light blue/grey

Perhaps more pictures with history. Like the family home, portraits of relatives. Create a story where they fit.

IMO the frames do not work with the decor and really the pieces are too small for where they are to hang. I like the idea of vertical on a narrower space . She needs bigger rugs and a new wall color but we need a lot more info.

If your Mom loves the art, please hang it up. Art is a very personal thing, and no one should be telling you not to hang your Mom’s art choice! Unbelievable. I’m not sure if you mentioned the size of the pieces, for anyone here to make an assessment regarding size used. But the art does not have to be any particular size. You could always add a piece or two to it, if your Mom wants more on the wall. Let her choose the art. The wood frames complement the nice wood window trim. If you added more pieces, you could stick with the wood frames or mix it up.

I'd reframe them with black frames and put them in the dining room or a guest bathroom.

I would rather see them hung where they can be viewed up close, but if that's what your Mom wants go ahead and hang them there. Pick colors from the pictures for throw pillows. I see pink and blue in the one shown, and either color will go well with the wall color. She will need to replace the throw with one in a softer color.

I disagree with the post by S. Alfin Interiors; black frames would not be appropriate for those pictures and I wouldn't hang them in a dining room or bathroom.

Those are framed needlepoint. I recommend that they be hung in a bedroom where their beauty can be appreciated. Hung together. Perhaps a bedroom where the bedding is ivory or white and where the color in the pieces can be utilized in pillows or a throw at the bottom of the bed. I believe the quality of these pieces is better appreciated when people can study them up close. Very pretty. And beautifully framed.

Again, please hang them where your Mom wants them to be hung. They do not need to be hung in a bedroom, bathroom, closet, etc.
