How to Make a Portlight Window Covers Video 2

The benefit of using these elastic portlight covers is that they effectively provide privacy when they are in place. They are also super easy to remove when you need a little more light or want to open the window. For our covers, we used a shade fabric that has an open weave that allows a small amount of light to still come through. If you want a darker shade, try using a heavier fabric like an upholstery fabric.

In this video, you’ll learn how to measure the portlights for the cover, pattern the fabric and sew up the covers. These covers include a sleeve with shock cord so the covers can easily be put on and removed with the elastic insert.

The best part of this project is how simple these portlight covers are to make. You can sew covers for all your portlights in no time at all!
