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.

any advice?

I am in PMB
