Whether the size of the house is small or big, the way it looks depends on how we design the interior. If you can change the colors and decorations of the walls and bring a new shape by moving things around at least once a year without keeping the same method, you can get rid of the monotony and give new life to the house and you can also get a hobby.
Illuminate the dark whole

A pattern for the wall with light

No matter how spacious the house is, if it is dark, it reflects that the space is blocked. This problem occurs especially in small rental houses. The best solution to this is to get proper lighting in the house.

During the preparation of the house, such places should be avoided by using windows, windows, etc., but the easiest thing that can be done to an already completed house is to light it with light bulbs. When using LED light bulbs that are not visible from outside, the power increase is very low, so they can be kept on continuously even during the day.

Other tricks that can be used for this are the use of white colors when painting the house, or a diffused light from the ceiling falling on a wall that does not receive light.
Use of mirrors

Different types of mirror designs for decoration

Mirrors are not limited to the bathroom and bedroom only, but by using them in the living room, you can get a better look inside the house. A mirror with an engraved, colored decorative rim/frame can add value to other colors in your home.

If the color of the paint on the wall is dark, a white frame is suitable, and for white walls, a color such as black or brown. If the rest of the furniture in the house is charming without carvings, the mirror frame should be chosen to be plain but outstanding.
Beehive Frames

Adding mirrors near the windows will increase the light, and if you have a beautiful garden, you can bring the outside environment into the house. Lamps throughout the house (such as table lamps) can be used to reflect the unwanted light falling on the wall back into the house.

Make use of the waste

We throw away many things, including clothes, kitchen utensils, and outdoor equipment. But once these things are arranged, you may not think that the living room, bedrooms and corridors are pleasant and suitable.
Hang broken ones on the wall

You can take a discarded teapot from the kitchen, remove the lid, put some beautiful flowers in it and place it on the small table in front of the sofa in the living room. If you have necklaces that you don’t wear now, they can be used to tie the door fabric as a holder. The wooden ironing board can be repaired and used as a table in the living room, and an A-shaped ladder can be used as a shoe rack.
More variation from small tables

Four-legged tables are a common thing in every home. But three-legged tables are very small and contribute to the design of the house by sitting in a corner. These can be chosen in wood, painted iron or rattan to match the rest of the furniture in the house. If it is used in the living room, it is better if the surface is made of glass.

A table lamp can be placed on a small table next to the bed or sofa. A slightly higher table with several layers is more suitable for the living room. Then you can place books or magazines on the floors below it. In addition, it is possible to keep decorative items on a table like this in a deserted corner, and to place commonly used family devices such as a corded phone or a tab.

A few messy pictures

The best way to erase the desolation of a wall is to decorate it with pictures. Family pictures or drawings can be used for this. If desired, pictures of stars taken from the Internet, European paintings, sentimental paintings, etc. can be decorated with interesting frames that match the other colors of the house and the texture of the furniture.

When storing these do not hang neatly in the same sizes like a grid of squares

By creating a pattern with different sizes (a large photo in the middle, small ones around as a circle, etc.) it is possible to bring a different look. However, it is wise to use a maximum of 8 or 10 photos to fit the size of the wall without using too much.

If the house has less space, instead of the space across the house for photos, the upper space can be used well by using shelves on the wall. If you are hanging pictures on the wall, using pictures that are longer than they are wide will give the house a taller look.
