I am trying to use finely chopped cotton strands as a filler instead of fibreglass.
It is for a hobby project and I do not like to use fibreglass.
there are lots of alternative materials but i find that cotton strands of about 1cm - 2cm long adds a great deal of tensile strength and is also cheap.
I have been to many fabric shops a carpet shop but no luck
it is easy to get waste material from clothing factories but fine strand or even 1cm square pieces would be perfect.
