Curtain and Curtain Track

Curtains are made of a banner with 1 string above it. These can be attached to curtain tracks, crafted with 3 gold ingots in a line. Curtain tracks must be places horizontally, and connect to each other like iron bars. Curtains can be placed on curtain rails and even on each other. You can move a curtain by right clicking it, and if you craft a curtain rail with red stone, you can make curtains move from one side to the other when red stone is activated on then. This would make for some good decoration for houses, and also allow you to make curtains for stages, controlled by red stone
