So when I asked them what they'd like to do over the summer, the top request was for Harry Potter day. Ah, OK. What does that involve then?
Well, first of all you need to find your Hogwarts uniform:
Then you need a wand, complete with a treasure for its magical core - one had a special fluffy feather, the other had a piece of wool from the mane of a very well loved unicorn.
(Instructions for wand making are here, though you really don't need them)
Not my proudest crafting moment but it did the job - until I sat on it.
For the first night feast you need to eat special magic biscuits decorated with appropriate symbols:
and you need to drink butterbeer - an alarming combination of cream soda and Nigella's butterscotch sauce which tasted far more delicious than it had any right to do.
Then, and only then, can you sit down and watch one of the films, for the fiftieth time. And if you're really lucky, you get to do it all over again the next day!
