I'm a big fan of Harry Potter and was inspired to create some bobby pins to represent the 4 Houses of Hogwarts. All 4 sets are available in my pandacub Etsy shop.
The 4 pairs of bobby pins encompass the House colours:
Gryffindor: scarlet and gold
Hufflepuff: canary yellow and midnight black
Ravenclaw: blue and bronze
Slytherin: green and silver
"You might belong in Gryffindor,
Where dwell the brave at heart,
Their daring, nerve and chivalry
Set Gryffindors apart.
You might belong in Hufflepuff,
Where they are just and loyal,
Those patient Hufflepuffs are true
And unafraid of toil.
Or yet in wise old Ravenclaw,
If you’ve a ready mind,
Where those of wit and learning,
Will always find their kind.
Or perhaps in Slytherin
You’ll make your real friends,
Those cunning folk use any means
to achieve their ends."
- J.K. Rowling
from Harry Potter and the Philosopher’s Stone
So, what House do you belong to?
