In a large bowl, mash the blueberries. Add raspberries and mash. (I just pulsed each of the berries a few times in my food processor) Stir in sugar and lemon juice. Let stand for 10 minutes. In a small saucepan, bring water and pectin to a boil. Boil for 1 minute, stirring constantly. Add to fruit mixture; stir for 3 minutes or until sugar is dissolved.

Pour into jars or freezer containers; cool to room temperature, about 30 minutes. Cover and let stand overnight or until set, but not longer than 24 hours. Refrigerate for up to 3 weeks or freeze for up to 1 year. Yield: 3-1/2 pints.
