The Charmed Knits one is pretty interesting; basic Molly Weasley sweaters with the gigantic initial on the chest, the school scarves/mittens, socks, some other stuff. But I don't know what's inspired these particular yarns.

You could certainly have your own Ron Weasley blankie to curl up under, be tucked into, this is totally going to melt your brain if I continue...

I could totally knit a good-sized blanket out of that. I wonder how much it would cost per skein...
