In this post about children in church, I mentioned that I give each of my children a little notebook for taking notes during the sermon.
Instead of buying new notebooks for everyone, I remembered that a lady at church had "rescued" 15 or so of those little week-at-a-glance calendars from a bank that was about to throw them out. She offered them to me, and I took them, thinking that I would surely find a use for them, even if it meant just letting the kids use them for doodle pads.
Since they are about half the size of a check book, I can easily fit 6 of them in my purse, and they ended up being perfect for the note taking I had in mind. We just ignore the dates and use them as we would a regular notebook.
