How do I decorate this wall above my dining set?

How about a couple of large cathedral "windows"? Then some greenery, possibly a large wreath in the center. This style table makes me think farmhouse. If that's not your style, let us know.

Here are some great dining room wall ideas for you! Lots to look at so you can find what you like! https://www.pinterest.com/explore/dining-room-walls/

3 paintings - please do not make the common mistake of hanging them up high. Rule of thumb when hanging anything - it should be at your eye level. If you are 10 feet tall hang it to the ceiling but if you are 5 feet hang it 5 feet from the floor eye level.

I would use something black with cream matting on the walls to anchor it to the pretty rug you have in there. VERY NICE room! Go to your local flea market and look at some of the paintings for sale there see what speaks to you don't be in a hurry take your time - they do not have to match but the colors should coordinate since your room is eclectic why not allow your paintings to be the same Add some black rolled throw pillows to your chairs to support your lower back while dining. Love the paint color Add cream sheers perhaps a sheer with a print to match the wall color tie it all together see JCP for that or if you are lucky find a Ollies they are sure to have your color

Hey, switch the placement of bench and the chairs, as well that way the chairs will not take away from the picture's and the throws will be a welcome surprise for your guest. If you like you can add 3 or 4 square medium pillows to the bench to support seating just make sure they are not to well stuffed and that they are square, I would find a pop of color for my pillows like a Orange, Teal or a Yellow

I like the idea of switching the chairs and bench! I just made my own wall art to go across a couch we have - I used wood and ordered a stencil to put on the wood. It has a gallery wrap look. It's a world map if you want to take a look - https://www.justmeasuringup.com/wall-art-ideas/. Basically you want something (or a set) to be a little shorter in length on both sides than the the table.

Do you have kids, grandkids or pets? These large engineering prints would be SO cute hanging on that wall!

Thank you Courtney that really good idea

Got these "windows" from Etsy. Also that wall would look good with a large vinyl decal about family or giving thanks. Amazon has some beautiful affordable ones. Just put large vinyl wall decals in Amazon.com search.
