In reply to Jennifer’s question about fitting 6 loaves into a standard oven – I set the shelves so that I can put three on each shelf, and then I switch them around (top to bottom) at the midpoint in the baking. It works well for me. I find that the bottoms of the ones that are on the bottom shelf first get browner and sometimes the ones that are on the bottom shelf second need a little longer in the oven than the first set. My loaves get plenty of thumping on their bottoms!
Happy baking! Karen
