Homemade Black-out Blinds

Blackout blinds are a type of blind whose sole purpose is to minimise light entering a room through a window. Often, this type of blind is positioned behind other window treatments and curtains and just used when the person in the room wants to sleep during daylight hours. Creating fitted blinds for each window is actually a simple project, and the results are blinds that are tight and easy to use, providing excellent light control options. Blackout fabric lining can also be used as the lining fabric on curtains and blinds when they are being constructed.

Measure the window frame, and add 1 inch to each measurement. The window frame surrounds the active part of the window such as the sash. The window frame is fixed and doesn't move. On the inside of the window, the frame should wrap the functional window. If your window doesn't have a frame, then add 2 inches instead of 1 inch to each measurement.

Cut your decorative fabric and blackout fabric lining to the same size. Launder and iron your fabrics before cutting to prevent future shrinkage.

Turn your fabrics face sides together, and sew a 1/2 inch seam around 3 sides. Clip your corners, and turn your fabric right sides out. Iron the seams. Turn the unfinished edges under 1/2 inch and iron. Top-sew around the panel 1/8 and 1/4 inch from the edge.

Measure the length and width of the blind, and cut hook and loop tape to fit. Attach the adhesive hook portion of the tape to the window frame. Sew the loop portion to the lining side of the panel. Sew two parallel seams to attach the tape securely to the fabric. Press the hook and loop together to secure the blind to the window frame.


Attach your hook and loop to the inside back edges of the window casing if the window doesn't have a frame. You can also add quilt batting between your lining and fabric and quilt a design over the panel. This will create an insulating quality to your blind. Blackout fabric is generally white in colour, and you can use this fabric as a lining fabric for your existing drapes by sewing an inside lining panel that fits the back side of your drapes. Several variations of blackout fabric are available, and each controls light penetration at a different level. Curtains used for blackout draperies should extend beyond the window width and height to provide best blackout coverage.
