DIY Curtain Blackout: Tips for Customizing Your Window Treatments

When it comes to home decor, window treatments play a significant role in setting the tone and ambiance of a room. Curtains not only enhance the aesthetics of your living spaces but also serve practical purposes such as providing privacy and controlling the amount of light that enters the room. If you’re looking to enhance both the style and functionality of your window treatments, DIY curtain blackout is an excellent option to consider. In this article, we’ll explore some valuable tips for customizing your curtains to achieve blackout capabilities, allowing you to enjoy complete darkness and privacy whenever you desire.

Why Choose DIY Curtain Blackout?

Before we dive into the tips, let’s briefly discuss why DIY curtain blackout is a great choice. While ready-made blackout curtains are readily available in stores, customizing your curtains offers several advantages:

  1. Cost-Effective: Making your blackout curtains can be more budget-friendly than purchasing pre-made ones.
  2. Personalization: DIY allows you to choose fabric, colors, and patterns that match your decor style perfectly.
  3. Satisfaction: Creating something with your own hands can be a rewarding and satisfying experience.

Now, let’s move on to the essential tips for customizing your curtains for blackout purposes.

Select the Right Fabric

The first step in creating blackout curtains is selecting the appropriate fabric. Look for heavy, tightly woven fabrics like suede, velvet, or even blackout lining fabric. These materials effectively block out light and provide insulation, making your curtains both stylish and functional.

Measure Your Windows Accurately

Accurate measurements are crucial to ensure your curtains provide full coverage and block out all unwanted light. Measure the width and height of your windows, allowing for some extra fabric for hemming and fullness if desired.

Choose the Right Hardware

To create blackout curtains that are easy to open and close, invest in high-quality curtain rods, brackets, and rings. Ensure that the hardware is sturdy enough to support the weight of your chosen fabric without sagging.

Add a Liner

One of the key components of blackout curtains is the liner. Sew or attach a blackout liner to the back of your curtain fabric. This liner enhances the light-blocking properties of your curtains and provides insulation, helping to regulate room temperature.

Use Blackout Curtain Linings

If you want to convert existing curtains into blackout curtains, you can purchase blackout curtain linings. These linings can be easily attached to your current curtains, instantly transforming them into effective light-blockers.

Create a Sealed Environment

To achieve maximum darkness, ensure that your curtains create a sealed environment. Pay attention to any gaps around the edges, and use curtain holdbacks or tiebacks to keep the curtains close to the wall, preventing light from seeping through.

Test Your DIY Blackout Curtains

Once you’ve customized your curtain blackout, perform a test by closing them during the day to check for any light leaks. Make any necessary adjustments to eliminate any remaining sources of light.


Customizing your curtains for blackout purposes is a fantastic DIY project that combines style and functionality. By carefully selecting the right fabric, measuring accurately, and using blackout linings, you can create curtains that provide the perfect balance of darkness and style in your living spaces. With these tips in mind, you’ll be well on your way to enjoying the benefits of blackout curtains that are tailored to your unique taste and requirements. So, roll up your sleeves, get creative, and transform your windows with DIY blackout curtains today.
