Sounds like fun, here's my desk list...
Paper...
bristles from shaving brush
steel wool
shavings from odd and assorted hard plastics
Bicycle grease (probably need some fiber assistance... Might need to try...)
plastic packing peanuts
carpet, other assorted textile materials.
Fun exercise... You should do another one for improvised water containers, and pre-disqualify anything remotely resembling any kind of pre made drinking receptacle.
