Hi Rachael!
Congrats on your new home!! It’s beautiful!
It sounds like you have already seen OMG We Bought A House, but it might be worth a rewatch for general inspiration! Our recent kitchen makeover, especially, embodies the vintagey vibes you seem to be channeling in that pic!
As far as getting bigger furniture, I recommend thrift stores, flea markets, and yard sales all the way! These are great places to pick up some key items without spending major money — especially items in the rustic, farmhouse style.
I think the living room you have is already looking good! The inspiration image you have features a lot of whites and wood tones, so maybe try painting those black shelves white and bringing in a wood table or some wood frames on the walls!
Hope this helps! Let me know if you have any more questions!
XOXO,
Kate
