Ultraviolet Business Card Flashlight

Step 3 Sticking it together

Peel the backing off the self-adhesive vinyl, and stick it to one of the blank cards, keeping an even border around each edge.  Turn it upside down, and carefully trim around with a scalpel or sharp hobby knife (the second picture shows it partly trimmed down the right side and bottom right corner -  if I had three hands I would have photographed myself cutting it as well!)  The third picture shows the finished card after trimming.
