Muji has a bunch of cool notebooks that I like to use. In my case, the more expensive/precious the notebook the less likely I am to put ideas down.

Baron Fig!

I use a dot grid Leuchtturm medium size. While I love rhodia notepads and moleskines, Leuchtturm managed to combine my favorite things about both. Holds up to abuse, great paper quality, pocket in back, satisfying snap of the elastic and just the right size for my daily notes and sketches.

I bought mine at the local Artist & Craftsman, but its available online as well: http://www.amazon.com/Leuchtturm-Medium-Notebook-Dots-LBL14/dp/B002TSIMW4/

Rhodia Dot Pads. The smaller leather/elastic strap one when I'm on the go and their bigger flip pads in office or at home for larger concepts.

I found a very nice Sketchbook at the Computer History Museum. There is the old IBM logo on it, I love it! It's dotted on the inside.

For sketching I'd go with plain paper over dot grid.

I've couple dot grid notebooks from Rhodia & Behance, and while they're great for UI wireframes & logo concepts, I wouldn't do any "regular sketching" there - the dots are still distracting.

Then it depends on what you use to sketch, for pencil/fineliners most of the regular paper notebooks like Moleskine plain notepad will do. If you want to use more heavy ink (markers) or watercolors, you'd be better off with some heavier paper (ie. Moleskine sketchbook).

As for caring for it - Moleskine price will likely make you care for it more than you thought :))

(i admit i'm a bit of a notepad/sketchbook nutcase - http://instagram.com/p/lP7DNTlC5t is my reserve stock :) )

I use the cheapest Cachier Moleskines, they sell in packs of three. Plain paper - fit great in your pocket. I always carry at least two of them with me. Here's a link:http://shop.moleskine.com/en-us/notebooks-journals/cahier/

I've tried 10+ kinds of notebooks. I'm a lefty and I've always found it hard to find a decent hard cover notebook that lays flat. A couple months ago I came across Baron Fig. Their sketchbook 'The Confidant' comes in grid (my fave), lined and plain. So far this by far meets my needs while sketching!

i have a dozen moleskines and a stack of cheap sketch paper from the local discount bookseller, but i mostly use blank printer paper or printed with a dot grid. I like using a nice Copic with it though, or a Wacom Inkling if it's important.

I'm not allowed to buy any new notebooks until I use up the 7 empty ones I've bought over the years.

So currently, I'm rocking a graph paper notebook from Walgreens.

Thanks guys!

I'm using stacks of my own handmade notebooks with dot grid pages – they're really nice, but it's not like I'm advertising or anything.

Rite In the Rain Water proof paper!!

Currently using a Muji grid-dotted one. Which is just fine for a cheap notebook. Ink bleeds through though so can't use both sides of the paper.

Previous to that was some conference swag notebook. Which was fine ;-)

Previous to that was a cloth bound whiteline grid notebook. I love the look of the paper, which works just as advertised. However it's a little too thin for me - sharpies blead through - and the binding I had didn't lay flat like my old Moleskine's (I've heard their bindings have improved - not tried them myself yet).

Previous to that was a classic Moleskine.

I'm probably going to go back to a Moleskine for my next one.

It doesn't have any kind of brand in it. 2 euros sketchbook. Bought from a chinese dealer.

I use one of these and keep it filled with a stack of 3×5" cards. It's an infinite, modular notebook :)

Love whitelines

Large format Bienfang tracing paper for projects and asset development. Field Notes for personal stuff.

I like the Steno Books form Field Notes. http://fieldnotesbrand.com/shop/ They're just big and stay open.

I carry a Moleskine agenda, which was on sale. I use it for writing on my way.

And for sketching, I just have a pile of good old A4 paper. After sketching, I scan everything to store in Evernote.

A lot of people here seem to like Dotgrid.

I personally use the Quattro, and have never looked back.

I use flexbook and is great!

A couple of years back a friend got me a Moleskine sketchbook. Haven't stopped using them ever since, I love it! A bit on the expensive side but they have quite good quality.
