Step 1: What You'll Need
Hang tags, brads, hole punch (I used one with a smaller hole than the standard hole punch--you can also use a tapestry needle to punch a hole big enough for the brad), bone folder and string.
Of course, you'll need some paper and a scissor to cut the paper.
You'll need your sewing machine too if you plan on sewing down the middle.
You can also sew the paper to the tag by hand.
