Do you have access to a gin? That would get it at least mostly clean, then hand picking would clean it up, so you could possibly use it for anything you want. Using it, as is, for a pillow, or anything that will come into contact through only a thin layer of fabric, chances are it the vm (vegetable matter) will poke through, and scratch skin. Some of the VM might draw bugs - or actually be bugs - so, most things I can think of, to use it (other than as fiber in
cob?) will require at least some cleaning.
