The foundation has raised $1.1 million since its launch, and Carrie Bickmore tearfully thanked everyone for their support.
"I want to say to anybody who is suffering from brain cancer right now, we will use this money, and I will use it to try and make your future brighter, so that is what I promise you we'll do."
There was so much demand for the beanies that they have now sold out, and Carrie said next time they'll order 'three times as many'!
"To each and every one of you who have bought a beanie, seeing all the pics coming up on social media, families and babies and kids and, you know, I don't know any of you, but I feel like I know you all," she said. "So thank you very, very much."
Well done Carrie!
