Rhodia No. 14 Pads
This is a perfect size pad for carrying in a bag or back pack. The paper accepts even wet lines from a fountain pen without bleeding. I like the grid pattern because of it's versatility. You can do accurate drawings with the uniform squares. And the squares facilitate orderly note taking by virtue of measured indentation. I've used various sizes of Rhodia pads over the years and have always been very happy with them.
