Bake pie shell according to package directions.
If you are making your own lemon curd, do that 2 hours ahead and refrigerate. I was running tight on time so I froze the curd for 10 minutes and then put it in the fridge for an hour.
Reserve 1/2 cup Cool Whip for stars.
Fold lemon curd and Cool Whip together. Smooth into pie shell.
Decorate the top with blueberries, raspberries and Cool Whip stars (I used the Wilton 1M Tip for the stars).
