I was thinking of that as a plan B.
Or looking into other materials like vinyl, ect.
I had a mate suggest leather as an alternative.
If I can do it in rubber it would prefer it, as it will look proper.
Thank you for the idea.
Please keep the ideas coming, Im open to suggestions.

I am trying 3mm neoprene at the moment.
It is much harder to stretch on my jig.
I think it will take a few days to wind it down. (I don't want to tear the rubber, Its under alot of tension at about 3/4 of what I want to stretch it out to)
