In blender, blend the strawberries, tequila, lemon juice, schnapps and triple sec. Add ice too if you want frozen margaritas. Otherwise you'll be pouring the mixture over ice.
Dip rims of glasses in lemon juice and then into salt or sugar. Pour frozen margaritas into the glasses, or add ice and pour margarita mixture over the ice.
Garnish with whole strawberries on the rims of the glasses.
