I have noticed some people asking what screen to buy. If you must have a pull down or hidden screen, then you probably have to go the store bought route, but if not...... Look into Doing It Yourself! There are many formulations out there from simple DoAble material available at Home Depot to very exotic paints custom mixed for your room and light level from guys that seem to be more chemist that HT guy. Here is a link to my "custom mixed" formula that allow us to watch the screen in daytime with full sunlight in the room, yet it looks fabulous at night or when the blackout drapes are closed. If you want more info, PM me, or leave a reply here.
