What a gorgeous room! Cromarty is so lovely- in my last house I was planning to use it, but here it’s just a touch too green for me, sadly. I envy you your lovely picture rail; mine has been developed out but at least they left the Edwardian coving! For the bookcases I love both Minnie’s suggestions above. The plaster is soft and playful and evokes rose gold. The pigeon is so effortlessly sophisticated and would really showcase books, treasures etc.

I had various woods in my sitting room including two old large pine bookcases. I painted them off white Little Greene Slaked Lime. They look so much better now. How about painting the one you have either in white or a shade to fit in with your bedding, curtains and flooring? This is a section of one of my very tall bookcases!
