Foils are another major type of wallpaper you might find to your liking. Besides having very pretty patterns, foils have a reflective quality that tends to pick up all the colors in your room. That ability to reflect can play tricks on your eye in a finished room. You may be able to see seams from some angles, when from another part of the room the junctures completely disappear. Because of the metallic nature of these papers they are more conductive than other styles of paper, so you ll want to take extra care when installing around electric plugs and switch plates.
Mylar papers are similar to foils, with a more muted reflective quality.
Mylar is more of a plastic-y, filmy material.
