Start with a standard guitar pick - it will be used to make a template.
Put the guitar pick on card stock and draw around it to make a template then cut out the shape with the kitchen scissors.
Put the template on the gift card and use a Sharpie or other marker to draw around the template on the card. I was able to get 4 picks from this card.
You can use tape and tape it on then cut around the template (tape is made it a circle around index finger then used to stick the back of the template to the card).
Cut around the markings or the template taped the card and you have yourself a new guitar pick!
