Try Crate and Barrel, West Elm

Ikea has great panels in 98" that come with hem tape for a easy solution

Hi jschro. Is it possible for you to post pics of the spaces in question?

Www.halfpricedrapes.com I love their drapes and the prices are amazing!

I have attached pics of the room as it sits now. I hope you can help with these. The two rooms flow together. There r two large windows at each end. Thank you for all your help.

HI jschro. Thanks for the pics. Several have recommended great resources for your panels. I actually really like those currently hanging in the dining area. I feel like you are also on point with the concept of panels that go wall to wall, so the thing left to do is find the panels you like. I feel like you need pattern, since the windows are at opposite ends of a very long narrow space. This will help to make the space feel less disproportionately deep by "advancing" the end walls. I would love to see you turn the dining table so that the arm chairs can be placed at the table. If there is a leaf, add it. You have the space. You need a LARGE piece of art opposite the door in the living room end of the space. LARGE! (minimum 50" tall)This will give you a focal point and help to define the separate areas and again, help minimize the perceived length of the space. Do NOT use a grouping of smaller elements. If you can find a retailer in your area who carries Left Bank Art, LBA is a tremendous resource for great looking reproduction art at unbelievable prices, but they are a trade only resource, so you can't buy from them directly, unless you are a designer or retailer. Let me know if I can help you with this. Lastly, it looks like you have no area rugs. Consider adding one to the seating area. Make it light and airy. It could have a large scaled transitional to classic pattern. Good luck!
