You're almost there! When your dough is thin enough, fold the whole thing four to five times, depending on how much dough you have. Once it's folded and there are layers stacked on top of each other (like a letter), cut pasta into strips using a sharp knife.
This is the fun part: you can customize the pasta however you like. To make fettuccine, as shown, cut your strips about 1/2 inch apart. To make spaghetti, cut the dough even thinner. To make pappardelle, a thicker pasta, leave about an inch in between.
