I feed the starter with 3/4 cup sugar, 1 cup flour, 2 tbsp potato flakes, and one cup warm water. Then I leave it out on the counter for 8 hrs. It gets all foamy or frothy. (If it's cold, put it in the oven with the oven light on)
When I'm ready to mix up the bread, I stir the starter with a wisk. And then pour one cup starter into my mixing bowl. Then I add 1/3 cup veg oil, 1 tbsp salt, 3/4 cups sugar, and 1.5 cups of warm water...stir that up with the wisk. Then I add 6 cups flour and mix it all together by hand. May have to add a bit more water or flour to get right consistency...but not too much more.
Once all is mixed into a lump of dough I cover the bowl with saran-wrap and then put it in the oven(with light on) to rise the first time for 8 hrs. Once that has risen I take it out and make 2 or 3 loaves and put those in loaf pans that have been sprayed with crisco for baking...Then I put the panned loaves in the oven(with light on) to rise the second time. The second rise may be 4-6 hrs depending. Lastly, I take the loaves out and set the oven for 350 degrees. Bake the loaves for 20-30 minutes. Use a bamboo screwer to poke in the bread to see if it is cooked through.
The way I do it, we feed it Friday night, make dough Saturday morning, make loaves Saturday evening, then bake Sunday morning. Even if they rise too much, don't worry - when we did it, they didn't rise any further in the oven.
