Blackout Honeycomb Shades for Irregularly Shaped Windows — A Perfect Fit at Last

Slanted, triangular, trapezoidal or arched — we custom-build cellular shades that follow every angle of your window. No gaps, no light leaks, no compromise.

"We only make shades for standard rectangular windows." — that's what other vendors told you.
The one shop that would take the job quoted a fortune and a six-week wait.
Then you found out their fabric options wouldn't match your home at all.

At BERISSA, irregular shapes aren't an exception — they're our daily work. As a factory-direct maker, we cut honeycomb shades to your exact window angles, in blackout or light-filtering fabric, with the same pricing and lead time as our standard shades.
