Is there a widget for Mac OS X dashboard that has bigger sticky notes? Is there a widget for Mac OS X dashboard to write down notes?

N.B. What I use now are yellow small sticky notes (I'm using 8 on several spots on the scren).

I really love them, but sometimes it would be useful to enlarge them and make them bigger rather than put several of them into one.
I'm using SimpleNote on my Mac and iPhone for pretty much all my note-taking. It automatically syncs notes between computers/devices, so might not be for you if you only want local notes. I find it's really convenient for accessing my notes everywhere, though.

It doesn't look like big sticky notes, instead you get a list view of your notes with a preview, from which you can open the entire note. I find it really pretty, but it might not be the aestethic you're after.

Edit: Forgot to mention that I use the DashNote widget on my Macs. There are other options as well, but they mainly come as stand-alone programs.
