October and L's birthday! We read the entire Harry Potter series this year and L wanted a "Harry Potter Party". We had an elaborate "Scavenger Hunt" complete with spell casting to find gifts, which were the components of a his Harry Potter costume and some books to go with it.
I made (!) a birthday banner and purchased a Hogwarts one, which is making a nice decoration in our home still.
Each person was sorted into their house when they arrived. They wore the sorting hat and fished into a cauldron for a slip of paper telling them which house they were in.
I made Chocolate Frogs and had Bernie Bott's Every Flavor Beans.
I also made Butter Beer & some "Wands". I also made a cake which did not look at all like an orange cat.... more like a flesh colored rabbit...sorta, but it tasted good.
I think my favorite thing was the expression on his face when he saw the banners up and the sorting hat on the table.
