Here is a draft of my design in progress: link to PDF. It's hosted on my site so I can update it and remove it when the final is done.
This borrows from the Cornell design, but puts the other pane on the right. I have trouble writing at the right edge because my hand is not supported, especially when holding the pad in my lap. So, why not put the primary note-taking area in the place that's easiest to write? Likewise, the large area at the bottom for summary or for extended title labeling. I may further reduce the area at the top to make more "prime" room.
Notice that the rules in the main area are set up for my cursive italic practice. That is customizable. The right pane has the same main rules but more subtle. The Cornell paper does not rule the secondary areas.
A feature you may notice is a calendar at the bottom. Makes it easy to date the page! For work and schedule stuff, can mark a week or range with a penstroke, too.
The top margin has very faint rules so it can guide placement of titles or caption, page, etc. I'm thinking of doing the same thing on the bottom area, but I'm not sure. That's what I'd like more suggestions on.
