Place blueberries and stevia in food processor. Puree until it is smooth. Pour 1 1/2 to 2 cups of puree on to center of Teflex or plastic wrap covered food dehydrator trays. Spread puree out on tray. Since edges can dry faster, the puree should be spread about 1/8-inch thick at center and 1/4-inch thick at edges.
Placed prepared trays into food dehydrator with the temperature set at 135 degrees F. Average drying time is 4 to 6 hours. When leather is dried, it will be a little shiny and non-sticky to the touch. Allow leather to cool and peel it from the tray. Cut into strips. Wrap strips in waxed paper and store in covered container.
