*cough* I can make flags.... l
I make them to order, although I cannot make them exactly the same as the LOTR official ones, for obvious reasons.
I made one for J to her own design...

I also have one that is
almost finished that I can put the pic up in a couple of days time (once pictures have been taken).
The advantage is, of course, you can design exactly what you want - as long as it isnt
exactly the same as the ones in the films I can make it.
Those mass produced flags are not very good. They are just printed on cheap fabrics and are not hemmed or anything. What I make is a quality product. Although, I dont know whether that is what you want?
