In this step you will take your cut and ground pieces and apply them to the sticky side of the contact paper that you have laid down over your pattern. As you can see, the numbers on your pieces will match the numbers on the pattern. Again, for simpler patterns this is not necessary. Press them on firmly so that when the cement is poured it does not get under the pieces. Also, remember that the side of the glass that is against the contact paper is what you will see when the stone is finished. In other words, your design is now facing downward.
