Shape the pasta. For pappardelle, cut rolled pasta into 1-inch-wide strips. For fettuccine, run the rolled sheets through the fettuccine setting on your roller.

Make sure to sprinkle flour over the cut pasta before you place another layer on top. If not using immediately, cover the sheet pan with a dish towel to keep the dough supple.
