preserving material banner

[HotI]

Hi

I have a large banner that i would like to 'preserve'. It is about 6metres x 1 metre and i think it is made from a cut up sheet. It has texta and paint on it. The primary school kids made it for the local fire brigade to say thank you for saving their school during the bushfires.

Is there anything i could spray on it to preserve/protect the writing on it?

Thanks,

Kate

Maybe you could ScotchGuard it? Do a patch test first. It won't prevent fading... but might protect the textas from being damaged by moisture etc. I'd take a panorama photo too.
