Help needed from bread makers! I've tried making bread a couple of times, and it NEVER comes out right. I even messed up the "no knead bread" that even a 7 year old can supposedly make. Its always too dense, and the outside is always so hard! Can someone tell me what I'm doing wrong? Too much yeast? Letting the bread rise for too long? Any easy recipes would be greatly appreciated.

I would like to make a plain white sandwich bread loaf, if someone can help with that. Thank you!
