Flat bread

Hi,

I hope someone out there has a solution to my problem.

My sourdough starter works amazing and bakes wonderful tasty breads.

The problem I have is I have to make my dough very wet to get the holes in my bread. It is a very messy process and the bread comes out wide and flat. Not the look that I'm after! 

When I make my dough less wet the bread looks beautiful but has a very dense texture.

I've left it previously overnight to rise, but then is comes out way to sour.

I would appreciate any suggestions.

Thanks in advance!
