Slytherin Common Room

As I am now in year 12 I now have a common room at school as a tribute to Harry Potter I have been making a Slytherin Banner to put up in there to turn it into the Slytherin Common Room. While this is great fun, what I thought would be a simple weekend project (5 hours max) has now taken over 9 hours and I'm still not done! So Photos of the will go up along with instructions to make your own banner, but be warned it takes a long time.
