Anything inert, I use couscous because its coarser and will crunch down if theres a tad too much.
porridge oats. crushed corn flakes the list is endless but avoid man made fibers such "wool" as out of the missus knitting box, they can burn and become a sticky mess up the barrel.
Or you could go th posh route and use pukka felt wads.
