Thank you so much for posting!! You have to let me know how the Phases of the Moon comes out this weekend!!
As far as your living room, it sounds like you already have the color palette picked out, so I would search out the items that you mentioned in the colors that you mentioned!
I tend to like a solid colored couch, then incorporate patterns in the curtains or rug. With a minimalist look, I’d opt just one subtle pattern for one item, then choose solid colors for the other items.
Good luck decorating!
