I've just completed this Ron Weasley doll as a custom order. He's wearing a Molly-Weasley-style Gryffindor-coloured jumper with an "R" monogram. He was unpleasantly surprised by the size of the spiders in the local park. You wouldn't have thought it possible in England, but there you are.
Harry Potter is available as a knitting pattern in my Etsy shop and I'm thinking about making up the pattern for Ron as well. That tiny jumper is surprisingly easy to knit!
