I have only been able to find lined notebooks with big spacing between the lines (8mm). I would like to have very tiny spacing (3 or even 2mm). I haven't been able to find them.
Also, I'd like to design my own notebooks with custom layout, so basically I'd like to be able to get a custom notebook with an arbitrary greyscale basis (whether lined, or with e.g. some text in the corner). To be clear I am talking about this being on all the pages of the notebook, not just the cover.
Is there a good online store that will print notebooks based on your custom design? (In the UK)
