The mission inspiration is a monthly challenge with 10 prompts or steps which is the brain child of Mike Deakin. I find those monthly challenge to be very daunting but recently he came out with a mini challenge that gives a word prompt on an index card. It is A to Z so in the end there will be 26 indexed cards. What I understand is these are to be indexed after each month so you'll have 26 cards to have when an idea for an art journal isn't forthcoming.
I decided to do each month's mini challenge on an 3" x 5" index card. For the letter A, the theme was Aquatic.
