Slice the strawberries vertically in 1/8" thick slices using a small knife or egg slicer.
Spread 1/3 of your cream on the bottom of your trifle dish using a spatula.
Add an alternating layer of strawberries and cake cubes around the bowl against the glass. Fill in the center with more cake cubes. Use up to half of the cake cubes.
Spread a layer of 1/2 of the banana pudding. Because the banana pudding does not have any artificial yellow food coloring and is natural and a dull beige, I prefer not to spread it all the way to the glass.
Spread a layer of blueberries around the outer edge against the glass.
Repeat the cream, strawberry/cake cubes, banana pudding, and blueberry layers.
Top with the remaining 1/3 of cream.
Place five blueberries evenly on the top of the trifle about 1" from the glass's edge. Fill in with single lines of blueberries until they meet in the center. Continue adding blueberries to fill in the shape of the star.
Place one strawberry with the point facing towards the center of the bowl on the five inside corners of the star. Add two more strawberries outside each of the five strawberries. Then add a row of strawberries all the way around the trifle.
Fill in the blue star with additional blueberries to cover any visible cream.
