I've always thought of a rug to be something that is placed on the floor to add a touch of warmth and comfort along with an touch of colour to a room, even sometimes being more practical rather than decorative.
However there is a growing trend of using rugs as purely decorative features to revitalise a home by hanging them on walls, these are known as decorative rugs / wall hanging / tapestry. Generally having little or no practical value, these rugs are mostly exhibited on walls in the living room or bedroom but can also been used on beds and as table, chair and sofa covers. Although I would always have to recommend made to measure sofa covers
if you wanted to restore an old sofa.
If searching online you'll most likely come across many Persian or Oriental styled rugs from Asia and other countries such as Turkey, Iran & Egypt with a few modern and contemporary designs here and there. I would definitely recommend buying a rug made from natural materials such as silk and cotton not only for quality reasons but also they have less environmental impact. You could also find a number of companies producing bespoke rugs, which are great if you are looking for a specific design, colour or size.
Decorative Rugs can be a stunning addition to your home bringing dramatic effects to every room, you can even change them with seasonal fashions and take them with you when you move. Use decorative rugs to spruce up your home - part 2
