Step 1
Create your template.
I chose to have my books small, using just one sheet of 8.5x 11 cardstock each book. I created a grid of four squares by 3 squares each square measuring 2.75" square. Create this grid on the plain paper. This left a 1/2" strip along the edge that i later simply cut off. Now take this grid and lay it on top of your cardstock, with the drawn grid side up, not against the cardstock. (the idea here is not to get pencil marks on your cardstock). Using your straightedge, to guide you along your drawn lines, use a bone folder to score the grid through the paper onto the cardstock.
