Not a big idea; just a rather tiny one that I'm surprised not to find in existence.
After an extensive search I find that composition books come in only a few different rulings: wide- or college-ruled with margin, a couple sizes of quadrille, and the occasional "special ruled" with an empty top half
for graphs/charts. It's nice that they'd think to make the "special" lineless drawing space, but half a page is too much for me, plus its lines only come in wide-ruled.
What I desire in a journal is to do just as many dictionaries have done: illustrate or otherwise doodle in the margins. Much as I can enjoy writing, text alone can become dull, and I may fall into -drawing- what's on my mind. It is at this point that I find those useless lines on the outer edges to be annoying. Compositions, as I imagine it, should take an alternative approach toward margins.
So, the basic idea in my head is all too simple: have a composition book skip the vertical lines, instead making margins by ending the horizonal ones. Of course, I'd also like to make sure that the margins are spacious, and that the lines are available in college-ruled.
I'd be glad to see it if this were already baked. Or is that what that open space on the top is -really- for? ;)
