You need: your starter, a big bowl, a small bowl, a spatula, a loaf pan, and a piece of foil. I start after dinner but before I get too tired, because there are a few steps that take about 45 minutes, and then I let it rise overnight. The dough likes 68-70 degrees and our house is about 63 at night in the winter, so I don’t watch the clock. If we built a fire, I leave the covered bowls on the coffee table overnight since it’s warmer in the living room. Since it only takes 1/3 cup of starter, I usually do two since I have two large bowls. Then I bake one in a loaf pan for sandwiches and one in a lidded enamel pot (dutch oven) for dinners. The damp towel is so the dough doesn’t dry out.
