    Guys,
    The upholstery shop doesn't know how to correctly upholstery this section. They stopped the upholstery under under the window then used a black rug to run down the floor. Has anyone done this upholstery and can give me an idea on how to instruct the shop on the correct way it should ne done.


    Thanks
