I'm looking for suggestions: I want a base material to use for a sewing cutting board. The board needs to be at least 4' x 6' and will be covered with a mattress pad and an outside cover. The base needs to be porous enough that I can stick sewing pins in it for sewing projects. The covered board will also be used for pressing sewing projects.

I thouight I would use fibreboard but was discouraged by a lumber yard employee due to the number of chemicals that might not be appropriate inside the house, especially if I was using an iron on the board.

I would suggest plywood covered with self-stick cork tiles. Then cover as you wish.
