Decor help?

How about some end tables with big gorgeous lamps? Maybe some big plants on the floor or hanging by the window? A standing bookshelf in either corner would fill the space and give you lots of storage.

Floating shelves and word art have had their day imho. How about bright white shiplap (even "fake" shiplap), updated piece of artwork? Or, peel-n- stick wallpaper in a large, bright pattern? More light falling on that wall would be nice also.

you could buy bookcases and put on the wall for books, decor, etc. that would fill the wall in some or else a large piece of art work to put behind the sofa

It appears the sofa is pulled out from the wall you could add a sofa table and add framed photos, lamps, etc

Why is there so much space behind the chair? Open up the floor space with the chair or love seat closer to the window. A tall floor lamp behind it , the table next to it and floating shelves at a height you can reach to clean. Add several pictures or artwork above that.

You could do both floating shelves and word art. Plants and accessories on the floating shelves and a lamp or two would add greatly to your area. Lots of space, I envy you! :)

A fun plank wall might be nice.

I would use shelves with a bit of greenery and candles.

This company sells self-stick planks: https://www.stikwood.com/?gclid=EAIaIQobChMIzbmDiqGC7AIVjrbICh3HAQGOEAAYASAAEgJ2GvD_BwE

You could also stencil the wall. There are so many stencil patterns you could use. Here you can see the stenciled feature wall in my bathroom: https://momhomeguide.com/currently-october-stenciled-wall-bathroom/

Add a couple of side tables with lamps and a large house plant on each side. Then add a larger picture. At least double what you have now or do a gallery wall with multiple pictures

There is a picture in this post of what I did with floating shelves: https://happydealhappyday.com/4-tips-redecorate-farmhouse-style-budget/

I also like the idea of installing some bookshelves - I would go with white. You could place some books in them, and style the bookshelves decoratively to look nice.

Floor lamp on the side next to the pulled out chair and on the other side of the couch, an end table with a pretty lamp and a tall real plant in the corner by the window. You asked what to decorate the wall with....I like your art but think something lighter and brighter and maybe a little bigger. I would not do a gallery Would look too cluttered, I think.

Some floating shelves would look awesome on that wall! And a larger picture!

A large wall clock, decals or a mural.

Light colour wall art in my opinion, white shelves will look great too.

Hello,

Another suggestion might be Mirror...? Bright cushion for the couch!

Wood floating shelves would be lovely!

I would place a large plant by the window, throw a bookshelf 1-2 feet from ceiling for favourite decorations/ creations/books, wood wall from planks or pallets (if you don't woodwork, peel-and-stick comes in a thousand different wallpapers, wood or rustic whitewash brick are my favs). You can stencil or stick a favourite quote or Bible verse over that or do a sticker of a pretty picture (vase, art, plants, you name it!). Whatever picture you stick or hang, you can create a frame for! Anything from scrap metal edge and fabric inside to duct tape edge (I like burlap) with chalkboard paint inside. Don't be afraid to hang something like light fabric scraps or your favourite watering can or fairy lights to achieve a visual effect you enjoy. If you put a window frame up over a picture or pressed plants, I'd hang curtains as if it were a real window. I would consider making/ finding/ buying a blanket for the sofa back that compliments/adds texture to your wall. All the best!

If you want large art and words, go to Kirklands. They have a wonderful selection of art for walls and tons of metal art too. Home Goods is another place you can find that kind of art.

I think you need some kind of entable on side by the window, Then get a nice lamp. Both Kirklands and Home Goods have lamps too.

Floating shelves and/or large artwork. A mirror would look nice

Is your sofa going to be touching a wall ?

I'm a huge fan of mirrors to open the space.

Light colors, new blinds, and open it up a bit.
