Just moved into a new house and need help decorating my library/study!

The room is large (about 24×27 ft) with a big red rug (14×12). It also has some awkward double stairs that I have to work around for now. I’m keeping my current furniture and rugs but want the space to feel cozy, warm, and a bit eclectic/vintage.

I’d love advice on:

• Wall, ceiling, and bookshelf paint colors

• What kind of curtains would fit a cozy library vibe

• Coffee table vs ottoman (and what style)

• Ideas to make the stairs look intentional

• Extra furniture, art, lighting, and accessories

If anyone is willing to suggest a mock-up layout or design ideas, I’d really appreciate it!

For style reference, I love the cozy, layered look of Caroline Winkler.

Thanks in advance!
