We had most fun just making all the props and costumes things in the days before hand and getting into the whole spirit of it.
So the costumes - Zoe was a mandrake
Kaya was Harry himself
Lana was Mrs Norris
Rene was Lucious Malfoy and pretty much looked exactly the same as usual
I was the fat lady from the Gryffindor portrait
Doug came as Mad eye moody and was in character all night. It was highly amusing and a great costume.
We had themed food. Cauldron cakes, ton tongue toffee, cockroach clusters, Mrs Wealsey's corned beef sandwiches, butterbeer etc.
Our downstairs bathroom was Moaning Myrtle's, who was making moaning noises mysteriously throughout the party
We had an owlery
And best of all, great company
