Everyone loves MOLESKINE notebooks but telling them apart can be impossible. I myself use a different notebook for each class, and decided to straighten myself out by laser etching the notebooks' covers. For each notebook, I included the name of the course and an illustration. Laser etching creates a beautiful relief on the notebooks' front and the end result is almost magic.
My friends and classmates all loved the notebooks and asked how I had made them, so I've offered to produce etchings for classmates.
