Hello Eric, I have seen this rubberised foam sheets - about 1 to 2 mm thick and as light as a feather - at Michaels, Wall Mart and other craft stores. Paid 89 cents for a sheet. Here in India it is dirt cheap. Comes in one side black and the other side white, full black or full white. Kids use them for school projects and here in India I see them sold on the road side as shoe insole inserts.
You print the lens hood on paper and then use it as a template on your rubberised foam sheet. There is an exact name for this sheet, just that I can't remember. I have also used it for making flash diffuser and bounce card. Regards.
