Love the fabric on the chairs do it on them all and then choose a color from there to get drapes in a faux silk and much fuller than what you have I can’t tell what is in the right corner looks spooky to me. I would get brighter art work and I might be tempted to get a new rug that is the right size for the LR and use that one somewhere else and use the colors from the DR chairs for pillows on the sofa one of these colors in a shag rug would look awesome

Thanks for the input...that's actually a silk tree in right corner and your are right, the artwork in the dining room needs to be brighter and I'm working on just that. The curtains are the same as the ones in the great room just without the tassel but since the dining room window wall is the first wall you see from the front door I want it to pop....nicer curtains would be great too.

Patricia, do you think quatrefoil chair backs or curtains would be overkill...and maybe a smaller coffee table?

Perhaps add a border of trim to your curtains in one of those colors you want to bring over. It will add color without over saturating the room with it. Browse this search for ideas and examples: http://www.houzz.com/photos/query/curtain-ribbon-trim
