Need Blackout advice

[corrina01]

My DDs room has a blackout blind (that was what was written on the box) but it still lets some daylight in even when I draw the curtains.

What can I try to stop the daylight filtering in, as it is very sunny today  , and she can't nap, she is talking to herself as I type this.

We cut black posterboard to size and taped it directly on the window. I've heard you can do the same with aluminum foil.

Thank you Melissa, I will try this

Aluminum foil works GREAT!!  Almost TOO good - it doesn't let a single droplet of light in, if put up correctly!!!

It made ds's room so dark, we actually had to remove some of it!
