Print out the Sock Monkey Pinwheel Printable square, and then cut only the dotted lines from each corner towards the center. Tip: I cut a little bit past the dotted line to make folding easier.
Using your hole punch, make a hole on the top of your striped paper straw and set it aside. Take your printable and hole punch every other corner and fold them one by one towards the center making sure the holes stay lined up. Push your brad through all the holes and open up the back part of the brad to keep everything in place.
