These are the easiest thing in the world to make. You will need no special skills, just a lot of tape.
Step 1: Materiels
You will need a spoon, a roll of electrical tape, an old tennis ball, a paper clip, and some duct tape.
Step 2: Bend the spoon
Bend the spoon so it breaks at the head.
Step 3: Tape the spoon
Tape the spoon with electrical tape on the ball.
Step 4: Tape the handle on
Tape the broken handle onto the head at an angle with duct tape, then wrap it up with electrical tape.
Step 5: Wrapping up. Literally.
Wrap up the ball fully with electrical tape.
Step 6: Making The Pin
Take a paper clip and bend it into a pin. Tape it where you deem fit.
