    In reading recent posts about Molly buying Ron ugly robes and 
not being able to make them magically I started wondering. There 
must be rules or laws in the WW world that allow for certain things 
but not for other things. Otherwise everyone could just zap up 
whatever they wanted and be as rich as Lucius Malfoy. WW has money 
and stores and stuff; if a witch or wizard could just pop some 
clothes out of their wands why would they need money or stores? 
Maybe most magical spells and charms and potions are just temporary? 
Does anyone know of a spell that is permanent besides Avada Kedavra? 
I think that some of the Dark Arts must be permanent because of 
Neville's parents. Any comments?
