How to Transform Sheer Roller Blinds into Blackout Blinds

Quck answer

Converting sheer roller blinds into blackout blinds is a simple process that can be done with a few materials and steps. Here’s how you can do it:

1. Measure your window: Start by measuring the width and length of your window to determine the size of the blackout fabric you will need.

2. Choose blackout fabric: Purchase blackout fabric that matches the size of your window and the color you desire.

3. Cut the fabric: Cut the blackout fabric to the size of your window, adding a few extra inches on each side for hemming.

4. Hem the fabric: Fold and sew the edges of the fabric to create a neat and finished look.

5. Attach the fabric to the roller blind: Use double-sided tape or Velcro to attach the blackout fabric to the sheer roller blind. Make sure it is securely attached.

6. Test the blackout effect: Hang the converted blind and test its blackout effect by closing it and checking for any light leaks.

By following these steps, you can easily convert your sheer roller blinds into blackout blinds, providing you with privacy and blocking out unwanted light.


Sheer roller blinds are a type of window covering that allows light to pass through. However, if you want to block out light completely, you can convert them into blackout blinds. This can be done by adding a light-blocking layer to the fabric of the blinds.

Step 1

Start by removing the sheer roller blind from its mounting brackets. Gently pull out the metal tips on each end of the blind from the grooves of the brackets. Once they pop out, place the blind on the floor, fully extended, with the street side facing up.

Step 2

Measure the entire length of the blind, taking measurements from the left, center, and right. Write down these three measurements. Also, measure the width of the blind from the top, center, and bottom, and record these numbers as well. Choose the largest measurements from both the length and width as your final measurements.

Step 3

Cut a piece of fabric contact paper to fit the final measurements. Peel off the backing from one of the bottom corners of the contact paper and press it onto the fabric of the blind. Starting from the bottom corner, use a dry sponge to press out any air bubbles. Peel off the backing gradually, pressing out air bubbles as you go, until the entire sheet sticks to the roller blind.

Step 4

If any areas of the contact paper extend beyond the edges of the roller blind fabric, trim them off.

Step 5

Tightly roll up the blind and place it back on the window frame with the contact paper facing the window. Pull and release the roller blind multiple times to reset the tension in the roller.
