Seitz Blind Fly Net/Screen Material

Took the Roller Blinds down to clean mildew from the Fly screen nets by giving them a light spray with very dilute bleach solution then rinsing, which we have done previously on various vans with great success.

For some reason this time round just one of the nets has taken on a distinct yellow tinge, which we have since found out is due to the bleaching effect and cannot be undone (BE WARNED).

Anyway, we are on the hunt for a piece of replacement fly net material to make up a new fly screen for the discolored one, which is a relatively easy thing to do (if you can source the material).

So far tried all local caravan dealers and online caravan shops to no avail. Tried local haberdashery shops who sell all kinds of net but not a suitable replacement for the caravan (mainly because they are too stretchy).

Also tried online sellers of 'fly screen netting', but the two samples we have received have been very plasticky with bigger holes and we doubt they will work properly in the roller blind.

So, just before we give up and put up with one yellow fly screen, does anyone know where we can get hold of original (or a good substitute for) the fly screen net in a Seitz Roller Blind.
