A quick fix to stop light from streaming past your curtains at the edges of your window involve changing the curtain rod. Choose a curtain rod that wraps around the window and allows your curtains to fully cover up the window so light cannot shine through. Using this solution reduces the need to use tape, Velcro, or pin curtains to the edges of a window. Also, make sure that you install the U-shaped curtain rod high enough to prevent light from coming through the top of the window.

Magnetic Tape

You can apply magnetic tape to the sides of a window and the back of your curtains. Placing the magnetic strips in strategic places, the tape helps your curtains adhere to the wall, increasing privacy and blocking unwanted light from coming past the sides of the window.

Apply Foil

Hiding out in your kitchen is a helpful solution to block light from coming through the top and sides of your window. Take a sizeable piece of aluminum foil and adhere it to your window where needed using painter's tape. It may seem like a strange method, but applying aluminum foil to the window reflects light, keeps your home cooler, and blocks light.

Install Blinds

Take the plunge and combine both curtains and blinds for a unique aesthetic and a method that will keep light from streaming through the top and sides of a window. Specifically, you want to install blinds that lockout light, offering privacy, and maintaining a darker and cooler home. Make sure your curtains are wide-set and are mounted high enough at the top to be effective.

Add a Valence

Placing a decorative valence above your window and a dominant set of curtains can help stop light from streaming past the top part of your window. Depending on the design of the valence, if there is extra fabric overhanging on the sides, it can help reduce light from coming through the sides of a window too.

Choose Wider Longer Curtains

It is possible to underestimate the dimensions of your curtain, especially when you fall in love with the material and design and figure you'll make it work in your home. If you choose a set of curtains that is longer than your window and elegantly falls to the floor and is also wider than your window, you can better stop light from coming through your window at the sides and top. Consider choosing heavier set curtains to better block light and keep your room darker and more comfortable.

How Do You Close a Gap Between Curtains and Walls?

You can close a troublesome gap between curtains and walls by installing a wrap-around curtain rod and hanging curtains that are longer and wider than the window they cover. You can attach the sides of your curtains to the walls adjacent to a window using tape, pins, or Velcro strips. If your curtains are hanging too low, adjust them so that the topmost part of the window is covered, successfully preventing unwanted light from coming through.

How Do You Make Curtains Overlap?

If you want to have your curtains overlap, be mindful of how you install them in your home. First off, you will want to select curtains that are extra wide and dramatic, and hang them via ring clips on a bar that allows one panel to overlap the other. You can pull your curtains together so that they overlap and pin them together with a practical or decorative implement, or use extra-long ties or cords. When using curtain rings, they should clip through both curtains.

Whether you have your window open or your air conditioner is on full blast, watching curtains billow about a window is less than desirable. You can stop your curtains from blowing about a window with Velcro. Carefully place strips of Velcro at the sides of your window where the edges of your curtains overlap. Attach Velcro strips to the underside of your curtains, so they line up with the pieces placed on the wall, and press the curtains firmly to the wall, so they stop moving. You can also add heavy weights to your curtains, so they are less likely to move.

How Do I Turn Off the Light in My Air Conditioner?

Ideally, you should be able to turn off the light in your air conditioner, unless the menu bar automatically stays backlit when in operation.

Otherwise, install a curtain set made with a heavier material and install a curtain liner to block out light.


How do I get rid of the gap between my curtains?

If the curtains are hung on a rod, you can use a rod extender to move the curtains closer together and eliminate the gap.

If the curtains are hung on hooks, you can use smaller or more hooks to bring the curtains closer together.

How do you block the light from the top of blackout curtains?

The best way to block the light from the top of blackout curtains is to use a blackout curtain liner. This liner is designed to block out all light, not just the light coming from the top of the curtain. It is typically made of thick, heavy fabric and attaches to the top of the curtain, providing extra insulation and blocking any light that might otherwise come through.

What goes over the top of curtains?

A curtain rod, finials, and/or a valance.
