I use pieces of UHMWP (Ultra High Molecular Weight Polyethylene), it's a nylon like plastic but does not absorb water like nylon.
Fairly tough but malleable, I rivet it to bits of steel to clamp over the jaws of the vice.
Will post a pic when I find them, not needed them for some time 'cos woodwork rules now.
I used to work in the bakery machinery industry, lots of the stuff used in food production, you could probably scrounge enough bits from that sort of place. Cutting boards are the same tiff too!
