Flooring as Art: Setting the Stage for Stylish Windows
Let’s talk flooring for a second. I know, you came for curtain liners, but hear me out. If you’re like me, you probably see your floors as a canvas—whether it’s a sleek hardwood, plush carpet, or bold patterned tile, it sets the vibe for your whole room. It’s art beneath your feet.
But what’s the point of gorgeous flooring if your window treatments let in harsh sunlight that fades colors and heats up your space? This is where blackout curtain liners come in. YouTubers who focus on home décor—like Lone Fox and The DIY Mommy—are obsessed with using blackout liners to keep rooms cool, colors vibrant, and ambience on point.
I’ve tested a bunch of these myself (and stalked more than a few YouTube reviews late at night), so let’s jump into the eight best blackout curtain liners that YouTube’s décor gurus swear by.

What to Look For When Choosing Blackout Curtain Liners
Light Blocking Power
Are you after total darkness or just a little extra shade? Look for liners that specify their percentage of light blocked—99% means almost total blackout; anything under 90% lets some daylight through.
Material & Texture
Most liners are polyester or blends. Polyester is durable and easy to clean, while cotton blends feel softer but may be heavier. Triple-weave fabric usually blocks more light.
Size Matters
Measure your existing curtains before ordering! Liners come in different widths and lengths; getting the wrong size means gaps (and light leaks).
Color Choice
White is classic since it blends behind any curtain. But if your curtains are sheer or lightly colored, consider grey or beige liners so they don’t peek through.
Installation Type
Some liners use hooks; others have rod pockets or tabs. Make sure the liner matches your curtain style—hook-on liners are easiest for most setups.
Care Instructions
If you have kids or pets, pick machine-washable liners for easy cleaning. Some premium options require dry cleaning—check before buying!
My Buying Criteria & Value Propositions
Here’s what I personally look for:
- Ease of Installation: I hate complicated setups! Hook-on or rod pocket is best.
- Light Blocking Ability: For bedrooms, go with minimum 95%. Living spaces can be lighter.
- Fabric Feel & Weight: If you want drama (think hotel vibes), go heavier! For casual rooms, lightweight works.
- Washability: Can I throw it in the wash? Essential for busy households.
- Budget vs Quality: Sometimes spending a bit more means better sleep and less energy waste!
To get value:
- Compare price per panel.
- Read real reviews (YouTubers show live demos!).
- Look at warranty or return policy if you’re unsure.
