Hmm. I don’t know if I know how to do that! Techie son is working away from home all summer, too. I’ll try a better description and maybe you can “see” it.
For example, I have one of those date planner books with like a week on two pages. There are several lines under each date. I wrote one year in a blue pen, then a green one, then a red one, etc. and we just layered the notations under the date. On one day, for example April 20, I have a notation that we saw our first pelican in one year (the blue one–I think that was 2004?) Then it also has a red note that we saw a wood duck, and a green one that the daffodils were up, but that it froze again that night. Some days we have several entries, some days just one, some none at all. We started this after reading about a similar book Thomas Jefferson kept. We’ve been lax about doing it the last couple of years of Intense High School Anxiety–we just have a few entries in our current book I’m afraid.
