Supplies: Yarn, paper mache cone (from a craft store), white elastic cord, paint/spray paint to decorate your hats.
Step 1.: Create a set of yarn pom poms to place on the top of your party hats.
You can see the full tutorial for creating yarn pom poms here
Step 2: Decorate your hats however you want. I decided to keep mine simple and just add a little white paint. For the polka dot hat, I just stuck on circular stickers, spray painted the hat, and peeled off the stickers after the paint was dry….revealing the cardboard.
Step 3: Poke a hole on each side of the hat with a nail (or whatever works!) Measure out the length of elastic cord that you want and thread it through the holes on either side of the hat.
Step 4: Using a glue gun, attach your yarn pom pom to the top! Enjoy!
