I don't have a large cutting board, but I do have a large table with a wood top
There's no reason to use a cutting board for making bread, in fact I would recommend against it. Cutting boards are not big enough for good kneading and they slide around. You are better off using a large flat surface which won't move around. As for what that surface is it doesn't matter much as long as it is clean and doesn't have materials which may come off on your dough. As an example many people use spray polish or furniture wax on their tables which would make the surface unsuitable for bread. You don't want to eat polish or wax!
