“The robes of Ilvermorny are blue and cranberry. The colours honour Isolt and James: blue because it was Isolt’s favourite colour and because she had wished to be in Ravenclaw house as a child; cranberry in honour of James’s love of cranberry pie.”
If you’re wondering what Ilvermorny is, I’ll just wait here for you, while you pop over to Pottermore and read up on the history of the North American witchcraft school.
I had originally wanted to put the Ilvermorny crest on the pie (and I did attempt it!), but there was too much detail for it to look pretty in the end. So instead I turned back to Pottermore for some more inspiration and settled on this quote.
“The only other object that Isolt took with her was a gold brooch in the shape of a Gordian Knot that had once belonged to her mother.”
Now, a Gordian Knot can mean different things. In some cases, it’s more of a ball shaped knot, or it can be a Celtic design like this. We’ve naturally gone for the Celtic version.
