Roll-down curtain

A roll-down curtain is like a big piece of paper that covers a window or a door. It's a way to make sure that people can't see inside your house if you don't want them to.

When you want to use a roll-down curtain, you pull it down by a string or a stick. It's like pulling down a big blanket over your window! The curtain is attached to the top of the window, so it rolls down smoothly.

If you want to see outside, you can roll the curtain back up. It's like when you unroll a scroll of paper.

Roll-down curtains can be made of many kinds of materials, like fabric, vinyl, or even paper. Some curtains are see-through, like a thin sheet, so you can still see outside when they are closed. Others are made of thicker materials that block out light and keep your room dark.

In short, a roll-down curtain is like a big blanket for your window that you can pull down whenever you want to have more privacy.
