Well, as I distract myself from thinking about surgery tomorrow, these bookmarks have come to be.

There is a pattern for the Hogwarts School of Witchcraft and Wizardry, and also a design for the American Wizard School, Ilvermorny.  You can make these in the house colours mentioned.

Presently the patterns are over here on Instructables.  When the contest ends, I shall post the patterns directly in this post.  Enjoy.  And please vote for them.
