Are you short of ideas to fill that white wall that is crying out for you to put something on it? Most people tend to fill these gaps with paintings, but a very interesting option is to use rugs to decorate walls, since their numerous shapes, sizes, styles, colors and prices mean that you have many options available.
However, hanging a rug on the wall is not as easy as hanging a painting. If it weighs little you can still use hanging systems more or less easy, but as soon as they begin to have a considerable weight, they will not resist simply gluing them to the wall or placing them with staples. In this case, it is best to place them in a frame that will be the one that will be fixed to the wall to hold them.
As for typologies, depending on the type of wall to be dressed you can choose between round, rectangular, square, hallway, tapestries (more similar to fabrics than to a carpet itself), esparto, wicker, velvety ... Of course, if you opt for pile or wool carpets, always choose them short pile, because the long pile ones usually do not look very good on the wall.
Although there is an infinite range on the market, here are a few ideas for your inspiration.
The classic of rugs to decorate walls. Being the most typical format, most of the walls decorated by carpets usually have this format, either placed vertically or horizontally, depending on the wall. Widely used in headboards or decorating the area above the sofa.
This type of carpet has a somewhat particular format and is far from conventional. Most of the time they are made of macramé and are usually hung on a stick that is fixed to the wall, often with a cord that comes out from each side.
They are very decorative in Mediterranean or neutral style environments, because although they usually have relief, their tones range from ecru, white and beige.
If your style is colorful, eclectic and with an oriental touch, rugs or tapestries with Hindu mandala patterns can give your living room a very particular boho chic touch.
If your thing is the Mexican or African aesthetic, try placing rugs in reddish and earth tones, with patterned designs characteristic of those areas. You will give a very exotic touch to any wall where they are hung.
If you flee from the overloaded and the overdose of color, you can opt for geometric rugs in little tones, which give a very decorative air to the wall as a picture. For a more personal or bohemian touch you can choose them with bangs.
It seems that hanging rugs on a wall is often at odds with more minimalist and contemporary styles, as they shy away from the wrinkles and folds that a rug can create on the wall.
However, an extraordinarily modern aesthetic can be achieved by using large rugs in harmonious tones as a frame, placing several neutral models next to each other without much pattern, or by making creative compositions, for example by framing the rug as a frame or placing several plain rugs on top of each other.
Another very interesting option is to place hallway rugs (narrow and elongated) on a not very wide wall, or placing several if the width is greater.
Another curious and original option is to use compositions of several rugs in the same space. Sometimes they can be on the same wall (either framed in combination with real pictures or forming a set hanging from a bar), or on different walls and surfaces, framing the whole.
In short, a lot of options for all tastes. Here are a few more images to convince you.
