Wall stickers are absolutely the best when you want to decorate your child’s room. Wall decals are much easier to apply to walls, but as they are more temporary décor for your walls, they are likely to wear and tear more quickly. Wallpaper is much more durable as it is seen as a more permanent option due to more time needed and skill to apply. A wall decal, also known as a wall sticker, wall tattoo, or wall vinyl, is a vinyl sticker that is affixed to a wall or other smooth surface for decoration and informational purposes. Wall decals are cut with vinyl cutting machines. Most decals use only one color, but some may have various images printed upon them. Wallpaper is a material used in interior decoration to decorate the interior walls of domestic and public buildings. It is usually sold in rolls and is applied onto a wall using wallpaper paste.
