Place a tea towel on your work surface and generously dust it with wheat bran, cornmeal, or flour. Gently place the dough on the towel, seam side down. If the dough is tacky, dust the top lightly with wheat bran, cornmeal, or flour. Fold the ends of the tea towel loosely over the dough to cover it and place in a warm, draft-free spot to rise for 1 to 2 hours. The dough is ready when it is almost doubled. If you gently poke it with your finger, it should hold the impression. If it springs back, let it rise for another 15 minutes.
