Another idea is to place 4-5 frames of the same size on a wall together. You can randomly hang them, leaving small space in-between each one to form a beautiful pattern. Hanging frames in stair patterns or in a line is becoming very common. Remember that you need to balance them well if they vary much in size, painting style, and colors.
Also, having separate lights for the frames is a good idea. In case you hang them together, a single, wide, and proper wattage light can be used. Opt for special decorative lights for frames and make sure they do not glare.
Now that you have read the aforementioned tips, you might be eager to spice up your walls with them. So, get ready with the right fittings and give your room an ultimate look.
