Wall decals, which are vinyl stickers that can be affixed to a wall for decoration, are the easiest and least expensive way to transform your interiors. Wall decals or wall vinyls are available in a variety of different shapes and designs in the market. Unlike painting, which takes a lot of planning and time, these can be installed easily and quickly without making a mess. Here are some useful tips to help you choose, position and apply wall decals at home. A surefire way to ensure that your wall decal fits in your room is to select one in an accent or tertiary color that already exists in your room. For example, if you have white and yellow accents in your bedroom like the image above, draw inspiration from the same – use white and yellow wall decal for a co-ordinated look.
