Suggestion: Write on the right hand page and leave the left page blank (that's the back of the page if you fold the pages over). Then go over the notes later

Suggestion: Write on the right hand page and leave the left page blank (that's the back of the page if you fold the pages over). Then go over the notes later and summarise or add details on those left hand pages. I used to do the colour pen/highlighting then. Worked for me half a century ago. No data format problems or need for legacy hardware either.
