If you own a home, holiday rental, or hotel room in Greece, you already know what unfiltered Mediterranean sun does to a bedroom at 6 a.m. — or to a guest trying to sleep through a July afternoon. Replacing curtains is expensive and wasteful when the fabric you already have is perfectly good. The good news is that a clip-in blackout lining panel lets you retrofit any existing curtain without touching a single seam. The video above by Crafts by Masmi walks through the full process visually; this article breaks it into clear steps so you can plan, shop, and finish the job in a single afternoon.
Why Blackout Lining Matters for Greek Properties
In Greece, east- and south-facing windows receive direct sun from early morning well into the afternoon for most of the year. In a primary residence this means disrupted sleep and faded furniture; in a holiday rental or boutique hotel it means poor reviews. Blackout lining blocks 95–100 percent of incoming light, reduces heat gain through the window, and adds a layer of acoustic insulation — all without altering the look of the room from the outside.
Clip-in lining is particularly practical for rental properties because it is fully reversible. If a tenant or guest damages it, you replace only the liner, not the entire curtain panel. It also means you can switch to a lighter sheer lining in winter without any permanent changes.
What You Need Before You Start
The materials list is short: blackout lining fabric (sold by the metre at fabric shops or online — look for a triple-weave or coated variety rated for full blackout), curtain clips or drapery rings with clips, a measuring tape, scissors, and iron-on hem tape if you want a clean bottom edge without sewing. You will not need a sewing machine, seam ripper, or any specialist tools.
Measure your existing curtain panel from the top rod pocket or hook rail to the hem, and across its full width. Cut your lining panel to match those dimensions, adding about 2 cm on each side so the liner sits behind the face fabric without peeking out at the edges. Iron-on hem tape handles the raw bottom edge in minutes.
How to Attach the Blackout Lining Step by Step
- 1
Measure and cut the lining fabric
Lay your existing curtain flat on the floor or a large table. Measure its height and width, then cut the blackout lining to those exact dimensions. Add a 2 cm allowance on both vertical sides so the liner is hidden behind the face fabric when the curtain is drawn. If the cut edge at the bottom looks raw, fold it over once and press a strip of iron-on hem tape to secure it — no needle required.

Finish the top edge with a fold or tape
Fold the top edge of the lining down by about 4–5 cm to create a channel or a clean header. Press it flat with an iron and secure with hem tape. This folded strip is where your clips will attach, so it needs to be firm enough to carry the weight of the fabric without pulling away over time.
- 3
Attach curtain clips along the top of the liner
Space drapery clips evenly across the folded top edge of the lining — roughly one clip every 8–10 cm works well for medium-weight blackout fabric. Clip directly through both layers of the folded header for the strongest hold. The clips should match or complement your existing curtain hardware so they are invisible once the curtain is closed.
- 4
Hook the liner onto the existing curtain rod or rings
Slide the liner clips onto the same rod your face curtain uses, positioning the liner behind the decorative fabric. If your curtains hang from rings, you can clip the liner directly to the back of each ring instead. Adjust the liner so it sits 1–2 cm inside the edges of the face curtain on each side, completely hidden when the curtain is drawn but creating a full seal against the window.

Test the seal and adjust if needed
Close the curtains in daylight and look for light gaps at the sides, top, and bottom. Side gaps are fixed by sliding the liner clips a fraction further inward. A gap at the top usually means the header fold needs to sit higher on the rod — simply unclip, reposition, and reclip. For the bottom, a curtain weight (a small lead weight sewn into a pocket or taped inside the hem) will pull the liner flush against the wall or sill and eliminate the last strip of light.

FAQ
- Will clip-in lining work with any curtain style — including eyelet or tab-top curtains?
- Yes. The liner clips attach to the rod or to the back of existing rings independently of how the face curtain is hung. For eyelet curtains, thread the liner clips onto the pole before re-hanging the eyelet panel so the liner sits flush behind it. Tab-top curtains work the same way — the liner simply rides on its own clips behind the tabs.
- What blackout fabric rating should I buy for a Greek summer bedroom?
- Look for a triple-weave or foam-back fabric labelled 100 percent blackout or "total obscuring" rather than just "blackout-effect," which can still pass some light. In Greece, where summer sun is intense even through north-facing windows, a coated triple-weave is the safest choice. Avoid thin single-layer blackout fabrics — they block less light and deteriorate faster in high UV environments.
- Can I remove the lining when guests leave or when I want to let in natural light?
- Absolutely. That is one of the main advantages of the clip-in method over sewn lining. Each clip detaches in seconds, so you can pull the liner off the rod, fold it, and store it until the next booking or until the seasons change. This makes it ideal for holiday rentals where some guests want full blackout and others prefer a lighter room.
