Yosef Karo

“ There are those who permit an item set aside from use even on a sacred holiday (Tur) . But a newly created item is forbidden according to their opinion, even on the Sabbath. And any item set aside from use that is not a living creature, such as a storehouse of produce or wood, it is enough that one says: "From here I am taking," and he does not need to make a sign (Rabbenu Yerucham) . And it is permitted to prepare from the first day of a sacred holiday to the second day on the two sacred holidays of the exile (Kol Bo) . ”
