looking for H.P. Merch- fabric, sheet sets, shirts in stores- ideas where at?

[Kela Hildebrand]

Hi, my son and I were looking for fabric/material to make pjs and
stuff out of but are unable to locate any in the fabric shops. Anyone
know which stores are allowed to carry Harry Potter items this time
around? Unable to find t-shirts and sheet sets either. 

I don't get it, usually there are several stores that have this type of 
stuff so you can actually look at it and not be at the mercy of people 
on ebay or other e-stores. My 9 year old is getting a bit frustrated 
since he wants to re-do his room and we just aren't finding stuff. So, 
I was hoping another fan/parent would happen to know anything, the 
official Warener-Bros site doesn't have much, tried that....any ideas 
are appreciated.

Thanks! ~Kela
