1. Measure your Windows

Before you can make regular curtains into blackout curtains, you will need to measure your windows. Start by measuring the width of your windows from one edge to the other, making sure to include the area where the curtain rod will be. Then, measure the length from the top of the window to the bottom. You may also want to measure the depth of the windowsill, as this will help you decide where to hang the curtains so that they will be properly centered. Make sure to write down these measurements, and double-check them to make sure they are accurate. With accurate measurements in hand, you will be ready to start the project and make your regular curtains into blackout curtains.

2. Cut the Fabric to Size

Once you have measured your windows and gathered all the necessary materials, it is time to start cutting the fabric for your blackout curtains. The first step is to mark the fabric with the measurements you took earlier. Make sure to double-check the measurements to make sure they are correct. After that, use a ruler and a fabric marking pen to draw a line along the measurements. Then, use a pair of fabric scissors to cut the fabric along the marked line. If you are using a patterned fabric, make sure to match up the pattern pieces before you cut. Finally, cut any extra fabric off the edges to make sure the pieces fit perfectly in your windows. With the fabric cut and ready to go, you can start assembling your blackout curtains.

3. Hem the Edges

To give your blackout curtains a neat and finished look, you will need to hem the edges of the fabric. Start by folding the edges of the fabric over by 1/4 inch. Use a ruler and a fabric marking pen to draw a line along the folded edge. Then, use a sewing machine to sew along the marked line. If you are using a patterned fabric, make sure to match up the pattern pieces before you sew. Finally, use a pair of shears to cut any excess fabric off the edges. With the edges hemmed, you are ready to move on to the next step in making your regular curtains into blackout curtains.

4. Attach the Hooks

To attach the hooks to your blackout curtains, you will need to measure the distance from the top of the window to the place where you want the curtain to hang. Then, you will need to place the hooks on the back of the curtain and mark the spots where you need to make the holes for the hooks (if your regular curtain already had hooks, just trace these holes in the blackout fabric to save time). After that, use a sharp fabric or leather punch to make the holes for the hooks. Finally, attach the hooks to the curtain and hang them up. Make sure to hang the curtains at the right height so that they completely cover the window and provide the necessary privacy and light blocking. With the hooks attached, you are ready to steam and iron the curtains and finish off the project.

Don't want hooks? Holes for hooks can sometimes let light through, defeating the purpose of an ultimate blackout effect. Transform your blackout curtain by trying a sewn-in rod pocket for 100% coverage, or velcro attachments for a portable and opaque option!

5.Hang the Curtains

When it comes to hanging the curtains, it is important to take note of the length and weight of the fabric, as this will determine the type of hanging hardware that needs to be used. Additionally, it is important to make sure that the curtains are hung with even pleats and that the edges are aligned with the window frame. Finally, once the curtains are hung, it is important to check that the curtains are properly insulated and that the blackout material is blocking out all light from the window. If necessary, the curtains can be adjusted to ensure that no light is entering the room. By following these steps, you can ensure that your curtains are hung properly and that the blackout material is doing its job.
