Pottermore Insider Blog: Creating House Crests
The Pottermore Insider Blog has been updated with a new post (the first of two) looking at how Atomhawk Design went about creating the Ravenclaw and Gryffindor crests.
“The starting point for each of the house crests was the Hogwarts crest, which first appeared on the title pages of the Harry Potter books, and represents all four Hogwarts houses. This original artwork and J.K. Rowling’s descriptions of the houses were used to inspire four unique house emblems for Pottermore.”
You can read about the overall process, see sketches and how they came to the final versions of the crests.
