Authenic Hogwarts Robe Patterns?

[Belinda]

Grant,
There's another yahoo group here:
http://groups.yahoo.com/group/MadameMalkins/?yguid=210261518
called Madam Malkins...
dedicated to discussing all the costuming.  There are some 
experienced folks here who have created and/or altered patterns. They 
are VERY helpful and eager to answer specific questions as someone is 
working on a project, if you want further advice.
Good luck!
Belinda
