Two tries - two lessons in how not to make a challah

Breads #43 and 44 - two lessons in how not to make a challah. Humbled, but wiser. Sometimes it is good to have a lesson when you think you have become experienced in something in particular. Not depressed, though, because - preview - bread #45, a whole wheat challah, came out fantastic. I will write that up soon. ow.ly/sS7PO

Any wise words on how to make a sourdough challah are welcome.
