Harry’s page has a new chart listing everything that he has received and given for Christmas. Well, that we know of, at least. I had fun looking for things that might appear again in Book 7.
Edit (8/19): the chart has gotten so big that the gifts Harry has given are now listed separately underneath the chart. And thanks to Bel there is also now a column for all the gifts Harry has received that weren’t given at Christmas or for his birthday.
