New Sketchbook!

I'm starting a new sketchbook today! You may remember it from my sketchbook cover project in Style School:

After filling up my old one, I finally get to use it! Underneath that adorrrable cover [;)] is just a regular ol' hardbound, plain, black sketchbook like this one:

I've used a lot of types of sketchbooks, and I can never decide which I like best. My last two were a thick-paged leatherbound, which was gorgeous, and a graph paper softcover that felt oh so lovely in hand (though the paper was thin). I think I actually bought both of those...I'm lucky enough to have friends and family who frequently gift me sketchbooks :)

I know my brother prefers a hard, black, spiralbound sketchbook:

These do lay flat, which is the basis of the appeal for my brother, I think. It's obviously easier to draw if you aren't having to fight your paper down. For me, however, the spiral gets in the way. I get all up in my sketchbook when I draw, haha!

Of course there are the much loved Moleskeins:

I love these for the fact that they are small, plain, and easy to carry. However, they don't lay flat, which can be an issue. And they don't have many pages. But I love them anyway ;) And it doesn't hurt that they come in a million colors!

There are a million options for sketchbooks, but the ones I've mentioned are my favorites :) [click the images for source]

What's your favorite type of sketchbook? What do you use?
