October Assignments

So the Harry Potter House Cup Oct. assignments have been posted and I'm having a lot of problems deciding what to make. I don't want to have to buy anymore yarn because 1. on a budget right now, preparing for Christmas and 2. I have a honking huge stash. But some of the assignments are requiring things I don't have such as dyeable yarn. Guess I will go stare at the stash some more and hope inspiration finds me.
