Clip approximately 1/4" of pages to the front cover of the book using clothespins or clamps.
Using a ruler and pen or pencil, draw a rectangle that will be used as your cutting template. Leave at least 1/2" around all sides that will serve as the edges.
Clamp the pages down that you'll be cutting.
Using the ruler and craft knife, make cuts on the lines you drew. Go as deep as the knife will let you go; don't try to do too many pages at once.
You'll be cutting out 10 - 20 pages at a time with a craft knife. Once you've cut out several pages worth, remove them.
Before flipping the pages of your book safe to make additional cuts, use the previous cuts as a template - draw another rectangle with your pen just inside the rectangle.
