Preheat oven to the lowest setting, between 150F to 200F, with the top oven rack in the middle position. Line a baking sheet with parchment paper.
Blend the berries and honey until smooth, adding lemon juice if desired. Strain to remove seeds if necessary.
Spread the mixture on the baking sheet in a thin, even layer.
Bake for 4 to 6 hours, until the fruit leather is no longer wet.
Cool for 4 hours or overnight, then cut and roll the fruit leather.
Store rolled fruit leather in a zip bag or airtight container.
