After you pick the template and arrangement- you can adjust the width of the sidebar and central columns. I think it is under advanced options in template designer. I changed the entire blog, then blogger had their several days of problems- and it reverted. So I got lots of practice. When you change the template, the pictures that are already on the blog will stay the same, so you'll have to change them manually if you want them larger.

Im excited to try those Lara bars. I can't eat rolled oats and have really missed my homemade granola and bars. This sounds like it might do the trick! My children are very attentive and aware of their diets, for similar reasons. They both have ailments that arise when they eat certain foods, and don't eat others. They both can recognize the effects and are careful to avoid them.
