I had the idea the other day (while listening to Harry Potter) to make Weasley Sweater icons for this Christmas. I did them in the four Hogwarts house colors: red & gold of Gryffindor, green & silver of Slytherin, blue & bronze of Ravenclaw, and yellow & black of Hufflepuff. I've spent roughly ten hours (spread out over a couple days) perfecting the "wool knit" texture (created pixel by pixel) and the lettering.
