If you hear a verse that you want to add to a page, jot it down on a post-it and put it on that page for later when you've got more time to be creative with it.
For example, if you're doing the #abcsofthebible and see a verse on "Rejoice!" that you want to incorporate on your "R" page, then write down the word and scripture reference on a post-it for later.
Stuck in traffic or waiting in a carpool line? Have one of your kiddos be your scribe and start a brainstorming game about words/phrases in the Bible that start with the letter-of-the-week. "B" is for... beloved, beautiful, blessed, beatitudes, brothers, etc. Then the next time you sit down to work on your "B" page, you've got some great starters!
