Mainstays Solid Blackout Curtain Panel, 1 Panel, White, 50" W x 63" L

These are actually blackout curtains and they help maintain temps. I have 5 sets if these white. Theyre thick and solid. They have white lining on the back. I have only had 1 panel that had tiny holes in the backing. It wasn't even bad enough to return. The white is white and I am not sure why others said the white was blue. I've never had a difference in colors and I've ordered them at different times over the course of a year. They do come stiff and wrinkled. I put them in the wash on rinse only in cold water, then I let them simi dry on the lowest heat. When they're just damp I take them out and hang them on the rod and let them finish air drying. I give them a quick spray with downy wrinkle release and when they're done they're barely wrinkled. This also softens them. The wrinkles will go away the longer they hang. It took about a week for my other sets to finally release their wrinkles. The ones in the attached pictures are brand new just hung and still damp.

The Mainstays 100% Blackout Single Panel Window curtain really works. It doesn't let in any light, even at the sunniest part of the day. Each panel is individually sold, so you would need two. Fit the window perfectly. The fabric seems very well made. No loose strings. I would definitely recommend to others. I'm really happy with this product.
