Postage stamps are made of paper, ink and adhesive. "Rubber" stamps are made of rubber or vinyl materials, but can be made from just about any material. Early postmasters in the US would use corks and even potatoes to make cancellation stamps.
they would put stamps in a frame and spread ink over the stamps and press the paper against it.

Originally, mail was stamped using ink and a stamp of some type. These stamps were made of wood, metal or in some cases, even potatoes! The impression indicated that the postage had been paid. When the paper stamps came out, they replaced the stamp, so got the name of the indication they replaced.

Textured paper can be put under pictures to add color. You can also stamp stamps on the paper and cut it out.
Grills were a method of breaking up the paper fibers. This allowed the ink in the cancellations to soak into the paper and made it harder to 'wash' the ink off of them.
Depends on the weight of the paper. Postage is determined by weight, not by number.
