Puree 3 cups of strawberries in a food processor. In batches, put puree in a strainer and push through as much juice as possible. Save juice and discard seeds.
Whisk together the sugar, milk, and cream in a medium sauce pan. Sprinkle the gelatin over the mixture and let sit for about 10 minutes.
Turn heat on very low and whisk mixture just until gelatin dissolves, about 10 minutes. Do not boil mixture.
Remove from heat and stir in strawberry juice and vanilla.
Divide mixture among the 8 ramekins and refrigerate over night or at least 6 hours.
In a separate bowl, mix together the remaining 3 cups of strawberries and the blueberries. You can add a little honey, if desired.
Remove ramekins from refrigerator and put in a "bath" of hot water (about 1 inch) for 20 seconds which will help loosen the panna cotta. Turn upside down on a plate and surround with the strawberries and blueberries.
