I had no idea you could do this!

Start by preparing your workspace. Lay down a plastic drop cloth or old newspapers to protect your floors from any drips.

Measure and cut the lace fabric to fit your window. Ensure that the lace covers the entire window surface for a seamless look.

In a mixing bowl, combine 1 cup of cornstarch with 2 cups of cold water. Stir the mixture until the cornstarch is fully dissolved and there are no lumps.

Using a paintbrush or sponge, apply a generous layer of the cornstarch mixture to the window surface. Work in sections to prevent the mixture from drying out before you apply the lace.

Carefully press the lace fabric onto the coated window, smoothing out any wrinkles or air bubbles as you go. Ensure that the lace adheres well to the window.

Once the lace is in place, apply another layer of the cornstarch mixture over the top of the lace to seal it. Make sure the entire surface is covered.

Allow the mixture to dry completely. This may take several hours, depending on the humidity and temperature in your home.

Once dry, trim any excess lace from the edges of the window for a clean finish.

For a more colorful look, consider dyeing the lace fabric before applying it to the window. You can also experiment with different lace patterns to achieve various styles, from delicate florals to bold geometric shapes. If you want a temporary solution, use a removable adhesive instead of the cornstarch mixture, allowing you to change the lace design whenever you like. Additionally, you can layer different lace patterns for a more complex and textured appearance.
