Beat remaining cup of cream with two tablespoons sugar and vanilla until stiff peaks form. Using a spatula, spread whipped cream along top and sides of cake. To create the star design: cut a strawberry into 5 equal sized slices with a small slice to cover the space in the center of the star. Place the strawberry star in the center of the cake and top with blueberries in a circular pattern. Halve the remaining strawberries and arrange in an outer ring along the edge of the cake. Refrigerate for 6 hours or overnight before serving.
