Thank you for posting this question and the links. Just last night I ordered 3 styles of chemo hats from a website to be delivered directly to the rehabilitation hospital my mother-in-law is in following removal of a brain hemorrhage. She has about 40% of her head shaved and a huge scar midline from front to back and then down along one side of her head. I'll be checking out these links for instructions and try making some in different colors after she is discharged.
