A small decorative collage typically consists of not more than 10 pictures. A larger family collage frame can provide space for even twenty or more photographs. If you don't know how many photographs you want to have, or you're just not sure yet whether you want to add more in the future, you can start to create your own collage. This involves getting individual frames for your photographs, making sure they are the same framing style and color, and hanging various photos in the same area of your wall. By doing this, you'll create your very own collage of photographs, without having to buy a huge frame. You can often buy frames in collage sets which include a variety of sizes for you to customize your wall.
