Shredded paper, packing beans, etc (Rose Hill OX4)

Hi all,
Strange request I know but my granddaughter is going to be doing/holding a ‘lucky dip’ at her school to raise funds for charity.
Does anyone have anything that can be used for the ‘packing’ - e.g. shredded paper, packing beans (or whatever they’re called) that you often find things packed with, or anything else that would be suitable.
I could even slice/dice old corks for her.
If any kind freegler has anything that they think could be suitable for this please do contact me asap.
The event is on 2nd of December so ideally she needs to be all ready by 1st December.

Thank you all.
