The Cup has classes based on the subjects in the Harry Potter books. Transfiguration is about changing the yarn in some way. Arithmancy can be about tessellations or other magical mathematics. Astronomy is about interpreting the celestial ceiling in yarn crafts. Herbology is about cables and patterns where the stitches resemble vines twisting around each other. Charms is about lace, lace, and more lace. Muggle Studies is about the magical communities interpretation of muggle devices and holidays. Care of Magical Creatures has involved studying creatures on desolate islands that have five feet or centaurs or other magical critters. History of Magic is interpreting the magical family trees in yarn and other magical historical things in yarn too. Potions is either studying a particular potion ingredient or the effects of a potion on others.
The classes have prompts to be worked on during the month. You are usually given a choice of 2-4 ways to complete projects for a particular class. The stories that the professors come up with to introduce the topic of the class are simply amazing. You really should check out the House Cup on Ravelry. One of the prompts had been about the idea of minitures and what would you need if you took an age reversing potion, what kind of items would your miniature self need to be able to survive. That was a neat story with lots of baby sweaters and doll sized projects, some of the doll sweaters for sale in my shop were featured in the Cup.
The Cup is a lot of fun, and a source of inspiration. I read all the class prompt stories. Then, I make at least one item for the classes. I am also working on what's called an OWL...in my case, it's a sweater for myself. I just have sleeves and neckline to finish. Today is the eighth of the month and I have until the thirty-first to submit that class and the OWL. I'm maintaining one class per month, sometimes more, so that I can be sorted this term. I would have been sorted for this term. I figured the headaches would give me pauses from knitting, so I asked to not be sorted after I had submitted my application. Anyways, the Sorting Hat was very accommodating and didn't have a fit when I asked to be unSorted.
This time around, next month, I plan to be Sorted, but am keeping the House name secret!
