COLLIER COUNTY, FL - "I don't think I've ever sewed anything quite as important to me as this," said Cindy Pereira.

Cindy Pereira has a personal interest in the safety of everyone at Calusa Park Elementary. Her daughter teaches first grade at the school. Pereira, who often helps in the class, saw something on the door that caught her attention.

"A roll of black construction paper rolled up and taped above the door. So I asked her what it was for and she said in an event of an emergency, I have to take tape and tape it down over the window so no one can see in," said Pereira.

That's when Pereira came up with a better idea.

"If you have black paper over your door how do you know whether its another teacher, a student, or somebody who's gotten in that no body knows about yet?"

So, she created a Quick Release Security Blind that's not just fire retardant, but removable, and easy to use during an emergency.

"It just takes one hand, and your hand operates it from above the window, rather than in the window, no body can see you do it, so while the lights are turning off, the blind is dropping by itself," said Pereira.

Pereira said it's so simple, but it gives her peace of mind.

"Anything for my baby girl too, if she needs something I would do whatever I can to make sure she's safe and those around her as well," said Pereira.

The school principal was so impressed, she ordered 80 blinds for every classroom at Calusa Park Elementary, which Pereira gave to her for free. The blind is weighted so it will drop by itself and remain in position. To order a blind, contact Cindy at WPM105@yahoo.com
