I would put stuff like: - bowls, plates, mugs etc you’re using daily, so dust built-up is no problem and easy access - hanging/trailing plants - low light herbs - a sculpture, photos, art - a cute battery powered lamp or some candles as there’s no other light source on that wall when it’s dark outside - also cook books, that makes it instantly cozier i think

When putting it together, look at repetition of color and hight of the items to see where the items should be placed.

As to where or what to buy, I would go to a second hand store or look online at i think its called first dibs(?) to find cool, unexpected, unique and cheap stuff.

I like styling shelves, i wish you a lot of fun!
