I have a pinterest board on this subject - link to decorating in blacks and grays and spent some time looking at my "pins" today - I found some wonderful images and ideas.
|I love the chairs in this photos as well as how they look with the other colors in the room - golds and blues - source link to source|
|Source for above three images|
|These French style chairs are wonderful and complement the warm colors in the room - I think the woodwork is a dark brown as well (not black) which suggests further options for upholstery. source|
|I have a piece of black velvet that I could use - this photo makes it look very doable although I worry about how much dust and dirt it might show. source|
|Here is a Suzanne Kasler (one of my favorites) designed space with a velvet sofa - source|
|Apartment make-over - love the pattern on the back of the chairs source|
I will have to make some choices soon for my "new" terrace-level space (aka basement - we don't like that word basement here in the South). Future postings on this subject to come including some before and after looks.
