Sewing a Leopard Cushion

This weekend I'm hoping to start-and-finish a cushion for a small bench. The fabric is a white and gray leopard spot that I bought from Pink Wallpaper's Designer's Attic back in October. The gorgeous image of Elvira Manrique de Lara's home from Nuevo Estillo will be my subtle reminder this weekend to get going! (Although I think those chairs are covered in a cheetah print?)
