White mesh fabric (Woodley RG5)

I want to repair the fly screen on a tent where it has split from the zip and I need a small quantity of white mesh fabric - not too light weight though.

Maybe from an old net curtain/petticoat/tu-tu/fancy dress etc. or even another fly screen.

I need 2 pieces which are about 61cm x 5cm

I am in Woodley and can cycle to collect from the surrounding towns and villages at most times,

Thanks, Chris
