If you have an awkward window or are just looking to mix things up, try this cheap and easy DIY project! All you need is some sheer fabric, cornstarch, and water to update any window in your home. Curtain sheers are the perfect fabric for this project. You may also use any solid or printed sheer fabric or lightweight lace. Cornstarch is available at any grocery store and just use tap water to make the paste. DIY cornstarch window treatments are affordable, practical, and durable.
It might sound too good to be true, but we have had cornstarch window treatments on our windows at home for over five years, and they still look as good as the day I put them up. I learned about this method while researching privacy window films online for our dining room windows. Our neighbor’s deck overlooks our dining room, and we wanted privacy but did not want to sacrifice the sleek aesthetic of our windows by installing curtains, drapes, or blinds. Window film would have been a good solution, but it was a bit out of our budget. Creating cornstarch window treatments was the perfect, affordable solution to our problem.
- Sheer fabric
- Measuring tape
- 2 tablespoons cornstarch
- 2 tablespoons room temp. water
- 1 1/2 cups boiling water
- Painter’s tape (optional)
Measure and cut the fabric
Measure the height and width of the window. Transfer the measurements to your fabric. Carefully cut the fabric.
Make the cornstarch paste
Combine 2 tablespoons cornstarch and 2 tablespoons room temperature water. Add 1 1/2 cups of boiling water to the cornstarch mixture. Stir together until the mixture thickens into a thin paste. Continue stirring as needed to avoid lumps.
Apply the paste to the window
Use a paintbrush to apply a thin layer of paste on the clean window glass. Cover the entire surface of the glass with paste.
Apply the fabric to the window
Carefully apply the fabric to the window as soon as the surface is covered with paste. The fabric will stick to the paste and you can adjust the fabric as necessary. You can use painter’s tape to help hold the fabric in place if it starts slipping. Once the fabric is in place, use the paintbrush to apply a thin coat of paste over the fabric. Use a squeegee to press the fabric into place and to remove any air bubbles or excess paste.
Allow the paste to dry
Allow the paste to dry and enjoy your unique new window treatments!
