I used the Jonathan Adler room I was wooing over as inspiration.
We already have the sideboard (the angled-leg sideboard from West Elm) and the chairs (the overlapping square chair from West Elm). The chairs are dark brown now but, going along with my goal to make things a little lighter and brighter around here, I'm going to attempt to paint them white.
I'm planning on buying similar-looking mirrors off Craigslist or eBay and spray painting them white. The screen grab of the painting is from local artist Brandon Mclean's website. I bought one his paintings a few years ago (not this one) but it has a similar retro feel.
Some succulents in vibrant potted plants and graphic blue fabrics (incorporated in a rug or some pillows?) would finish it off.
*A really useful tool for making mood boards is mydeco, by the way. It's come in handy for me...
