Made these this week.
The hat actually fits, it looks small because there's a foam cone ($1 at micheals in their Christmas section--it's brown) underneath that doesn't fit my head, but the crochet part is longer to fit. It is wavy around my face.
Pattern from the website The Leaky Couldron (an HP site) in their craft section.
The wand is from the dollar store, it had a foam star on the end, and I just taped it up and then crocheted over it.
All done with an H hook. Red Heart yarn in Black.
