Very useful to jot that special thought or two and keep moving.
I have not use these, but I plan to use them to write notes in the engagement calendars to explain events my mother wrote in them from the 1930s to the 1930s. I just couldn't throw these calendars away, but they will mean nothing to future generations if I don't write notes to the calendars. Hopefully this is a good idea. the Blanks seem to be the perfect size for this.
