We don't actually know how many cards you'll need to make. We're still doing user-submitted card prompts (people will be able to fill in a form if they don't know how to make the cards) and that's what you'll work on. Unlike 2012, we are limiting the number of cards each person can submit through the form. But... Dawn expected maybe twenty cards in 2012 and we all know that's not what happened. The easiest thing for you to do with limited time is to give us a number of cards per week you think you'll be able to make and we won't send you anything beyond that.
