Step 1: Supplies
Scissors or Exacto Knife
Scotch Tape or Super Glue
Step 2: Get the File
Things exist on the internet for free sometimes. The heart used in this tutorial is one of these:
This file is part of the Wikimedia Commons. Sort of like saying "it's cool if you've got plans for this file."
I took it into Photoshop erased the names of valves and made everything red. What a plan.
Step 3: Print the Hearts
See below for "hearts.jpg"
Step 4: Print the Words
Remember that you're going to press these two transparency sheets together, this means that your text will have to be mirrored/flipped horizontal/backward/inverted, you get it.
Print this file on a second transparency sheet.
See below for "text.jpg" to use the same file as this instructable.
Press these two transparency sheets together.
Step 5: Cut
Follow the border on the original heart print. Leave some red if you'd like.
You can tape the edge to preserve the words and the original shape of the heart print.
Step 6: Distribute
Since you made two, you can try it both ways.
Distribute to each of your valentines.
