Try getting your hands on a blue traditional rug. These might be from an older stock or might have been modeled after them. Rugs have been made in the near east with blue dye and an intricate weave for hundreds of years and were once a luxury import. They are still associated with traditional furniture and conservative, even Victorian interior design. A blue rug with diamond patterns look luxurious even if they came from a more common source.
Visit a website that sells quite a few different styles of rug. They are attractive, comfortable, and might be cheaper than buying from retailers. These rugs are kept in a warehouse until they are shipped. The lower overhead can mean excellent price savings on many products. The price of delivery does count, but buying direct from a warehouse might still be the far superior option.
