Normally I don't open the sheers, but thinking I might like to on occassion. So if I put the sheers on a decorative rod, how do I hang the drapery panels? My old drapes had a swag valance - very formal - that covered the top of the sheers where the pleats are. Now that would be exposed if I don't do a valance and not sure how that would look with a rod over it that the drapery panels go on. Hope this makes sense.

The colors in your picture are very hard to discern on line, so the actual color palette would have to be adjusted to match your particular colors and room conditions, but I would start with a rug...perhaps this one. ...then pull the colors from the rug to paint the room. Swap the drapes out with something in the color scheme but more in keeping with the furniture...a valance and side panels in a heavy textured fabric...maybe a velvet or a dupioni silk. Then go for art, perhaps something in the hudson river school that reinforces the color theme. I would add a separate but coordinating carpet under the dining room table.

I would do a pale blue l;ike the lamp base in a faux silk with grommets to keep it from looking too stuffy then add some pillows with the blue and other color. You really need art and the coffee table is not serving anything it has to be near one or the other sofa so pick one and then add 2 end tables to the other one.

I would work with the colors from the chair fabric. It and the pillows have some teal or aqua so look for things in those watery colors but darker or brighter. You also can rotate other colors on pillow covers. I switch mine seasonally to brighten our brown leather sofas. With cool greys and teals you could add warmth with accents of yellow or coral. Pick colors that you love. Maybe start with a large colorful canvas for the wall and use colors from it. You could even paint your own abstract. Stack a couple books under your lamps if you need them taller. Buy used books with colorful covers or recover them in paper to match your color scheme. Before investing in big items like rugs and drapes, try a few little colorful items like a throw to see what colors you like. Take your time to collect things that speak to you not just the latest trend.
