Long Curtains / material & Underlay (Mapperly NG3)

Hi everyone
I'm looking for some long curtains or material for my friends caravan please.
It's so he can divide the space making it easier to heat the smaller space and contain the heat.
Wide or long lengths of material or a lightweight throw or wall hanging that we can repurpose into some dividing curtains.
It doesn't have to be pretty to do the job and keep him warm, so anything is appreciated.
Ideally the curtains or material need to be light and not to heavy so they are easier to hang in the caravan.
Also looking for a bit of carpet underlay for the floor if anyone has any odd bits left over please.
Thanks In Advance Everyone
