Hogwarts Party Favors

Give practical party favors that the party goers can wear throughout the evening and take home the next day:

Once all of the Hogwarts students have arrived for the sleepover, gather kids together to have the Sorting Hat choose which house they'll belong to for the remainder of the party.

For favors, hand each wizard a tie in their new house's colors to identify who belongs to which house. At the same time, present them with the second part of their party favor - a wand they can use to cast charms and spells.
