Sheer curtains softly diffuse light

They provide privacy while allowing light to enter your home. Sheers can be use on their own or layered with panels.

After getting a few free swatches to figure out which color worked best in the room I bought two different lengths in order to cover the window without blocking the AC unit. They look great and I love the fabric and color choice. The grommeted option also gives it an elevated look.

I replaced my other curtains with these because I wanted a specific length. These blackout curtains look fancier than my old ones. Also the material feels heavier. We got the grommeted ones which made a big difference. I would defenitely buy these again.

We needed custom length blackout curtains that wouldn't block our heater in a bedroom.  Found this site and ordered 2 swatches. We ended up getting both colors for two different rooms.
