How to cover top of blackout curtains？
To cover the top of blackout curtains—especially to block light leaks and create a polished look—here are several practical and stylish options:
🛠️ Functional Solutions to Block Light
These focus on eliminating the light gap at the curtain’s header:
| Method | Description | Pros | Cons |
|---|---|---|---|
| Valance or Cornice Box | A fabric-covered board or structured box mounted above the curtain rod | Elegant, customizable, blocks light | Requires installation, may need custom sizing |
| Curtain Header Seal Strip | Foam or rubber strip mounted behind the rod to seal the gap | Inexpensive, effective light block | Not decorative, may need trimming |
| Double Rod with Sheer Overlay | Hang sheer curtains in front of blackout panels to soften top light | Adds depth and style | Doesn’t fully block light unless paired with valance |
| Rod Pocket or Hidden Tabs | Use curtain styles that sit flush with the rod (vs. grommets) | Minimizes top gap | Limited to certain curtain styles |
| Ceiling-Mounted Track | Mount curtain track directly to ceiling so panels start at ceiling height | Eliminates top gap entirely | Requires ceiling installation, not suitable for all rooms |
🎨 Decorative Enhancements
These add visual appeal while also helping with light control:
- Fabric Valance: Soft, gathered or pleated fabric that matches or contrasts with the curtain.
- Wood or Upholstered Cornice: Adds architectural interest and hides hardware.
- Decorative Rod Covers: Some rods come with built-in covers or can be paired with clip-on shields.
🧵 DIY Ideas
If you're handy, here are some creative options:
- Attach blackout fabric to the back of a valance for extra light blocking.
- Use adhesive Velcro strips to attach a fabric flap above the curtain rod.
- Install a tension rod above the main rod and hang a short blackout panel or flap.
