I made up the template then scribed the shape onto the ply offcuts then onto the bandsaw. 
Next step was the drill press for the four holes and holesaw for the centre hole. 
I used my small vertical linisher to sand everything 
Lots of repetitive processes, but always good to help my wife with props for the Kindygym program

Life’s Good, Enjoy Each New Day’s Blessings
