Love the subtle pattern, definitely blockout materials, makes a very cozy dark room. Wish the top tab had more stiffness as I can't hang the curtain high enough to fully hide the track because the top of the curtain would sag. Otherwise, a very good choice for a guest bedroom.
Overall they are brilliant curtains but a lot of the backing ended up on front of curtains during washing. They have certainly cut out the drafts and are definitely blackout so I'm super impressed with them.
