I use these to create dark hallways in my basement for Halloween and they are great. Not exactly opaque, but they do block good light that isn't directly next to them - and using light from behind can be a great effect too! Ordered a few more because they worked so well. I wish they were a little narrower (my ceilings are about 8 feet tall so I can hide a little more in the back), but I like 12 feet per section.
