Preheat oven to 400°F.
Mix the sugars, flour, nutmeg, and salt in a small bowl. Mix the berries in a large bowl. Add the sugar mixture to the berries and stir to mix. Let sit about 10 minutes.
Spoon the fruit into the pan and spread evenly.
Roll out additional pie crust and place on top of berries. Here are some options:
— Make pie crust art, using cookie cutters or a knife to cut out different shapes and place on top of fruit. This is a perfect pie for using art to send a message!
— Make a lattice top crust
— Make a traditional double-crust pie. Place top crust on fruit and pinch the edges to make a tight and pretty border. Cut some slits in the top to allow steam out.
Bake for about 50 minutes. Fruit should be bubbling around the edges and crust lightly browned.
