Tartine problems with crumb

Toast

I made a Tartine loaf; the outside looks great and bread taste great. I'm not happy with the crumb. I always seem to get a few really large holes. How can I get hole structure more evenly distributed, any suggestions, or am I expecting to much.

 

The holes look like shaping and degassing. For a more uniform crumb degass the dough more after bulk fermentation. Seal your seams well during shaping making sure not to trap extra air in a fold. Use as little flour as possible to prevent a spots that wont seal during shaping.

I suspected that the problem was in shaping and degassing I think I have been to afraid of handling dough to rough and destroying what air pockets I had already. I use very little flour but it only takes a small amount to prevent spots from sealingl. I'll have to keep these things in mind for the next timel

Thanks.
