Seeking Dust of Appearance

[Desicardo]

I am seeking a recipe for, or someone that could tell me where to find "dust of appearance".  I need 3 or 4 of these dusts to use in my bow making.  If you know what is needed to make it, I can collect the components, but I have not been able to find a recipe anywhere for this item.  I remember seeing it somewhere but I am unable to place where I have seen it or heard it referenced.  Catch me around Hlint or send a bird if you are able to help.
Thanks,
Armolas Folian

You can make it in Moraken's Tower . . .

Dust of Appearance is created by breaking copper into very fine powder and then infuse it with threads that hampers invisibility weaves. The process has to take place when... Actually, it's not all that complicated!

I can do that for you if you want.
