dying door card fabric...help please

[golfpro]

I have changed my interior in my mk3 now to the aniversary edition one but had to keep my old front door cards in for the manual mirrors and windows.I want to die the material in the door cards so they are black like the back ones. Can anyone recomend anything to use and how to do it?

thanks in advance for your help

get some black ones from a scrappy, easier, less messy and all round a better idea!
