So what's a card sketch? Basically an idea starter, a springboard to whatever you want. On those deary days when you can't get anything going, when inspiration is dry as a bone (and yes, we all have those days!) I reach for a card sketch. It gives my imagination a starting point. You can add or delete elements, flip or rotate the sketch. Sometimes the resulting card looks nothing like the sketch, but that's fine. It's cool. In other words make it your own. Sketches are just another useful, and free, tool to help the card maker along.
