Living in Northern Indiana I've always had a problem finding a warm place in my house for dough to rise. I've tried using my oven but it's usually too hot and then you can't preheat the oven while the dough is rising. My mother-in-law shared a trick with me that works perfectly every time - the kitchen sink!
Fill your sink with the hot water from your faucet. Place your bowl of dough in the water and cover with a cutting board to weigh it down. If rising a pan of rolls just set the pan over the sink and let the sides rest on the counter and cover the tray with a towel.
