Step 2: Print and Cut
Download the PDF below and print out at least 5 copies. You might as well make it 6 or 7 if you're new to this type of stuff. The thicker the paper the better. In fact, I'm using Bristol board which is basically card stock.
Once you've printed them out, cut out around the whole shape and the little black line in the middle.
Note: the file looks different because I updated it with the instructions on the page itself.
Also, I made the template as big as I could for a letter-size piece of paper. This makes a big star, about 17" wide. Since others would likely want smaller stars, I also made 2 other PDFs at 66% (11.5") and 50% (8.5") the size of the original. This allows for more pieces to be printed on each sheet.
