ATTENTION TO SCALE. A moment that at first glance seems obvious, but is not always respected - the proportionality of details to the interior as a whole. So, a huge picture in a small bedroom will look like an alien element, like a miniature sofa in a spacious living room. DECOR EXCLUSION METHOD - THIS WORKS. In rooms where decor is redundant, it is worth trying the method of exclusion - just remove some of the little things. Leave only the most colorful, but at the same time simple things, the presence of which really benefits the interior. The free space looks much more comfortable than it is filled with knick-knacks. EACH ROOM IS A SPACE FOR A SPECIFIC PURPOSE. In the process of decorating, it is important to remember that any room is a shell of space and time, designed to achieve a specific goal. Decor, like design, should fit this space - match the way people live in it.
In the Middle Ages, upper class Britons and other European nobility in castles or large manor houses dined in the great hall. This was a large multi-function room capable of seating the bulk of the population of the house. The family would sit at the head table on a raised dais, with the rest of the population arrayed in order of diminishing rank away from them. Tables in the great hall would tend to be long trestle tables with benches. The sheer number of people in a Great Hall meant it would probably have had a busy, bustling atmosphere. Suggestions that it would also have been quite smelly and smoky are probably, by the standards of the time, unfounded. These rooms had large chimneys and high ceilings and there would have been a free flow of air through the numerous door and window openings.
