Rinse strawberries with cold water, gently (but thoroughly) pat dry with paper towels, set aside. Line a small-medium baking sheet (something that will fit in your fridge) with aluminum foil.
In a microwave safe bowl (or double boiler) melt chocolate chips with shortening and stir until smooth. Carefully dip strawberries into melted chocolate, turning all the way around so that ll sides are coated with chocolate. Place on prepared baking sheet.
When all strawberries are dipped, place baking sheet in the fridge to cool. Add a few drops of food coloring (color of your choice!) into the melted chocolate (if it has begun to set up just put it back in the microwave on half heat for a few seconds and give it a stir) and stir until smooth and coloring is even. Remove strawberries from fridge. Carefully transfer colored chocolate into a zip lock bag, seal it and snip off just a tiny bit of one bottom corner. Drizzle colored chocolate onto strawberries in any design you like. Top with sprinkles. Return to fridge for about 10 minutes to set up. Store in airtight container in fridge up to 3 days.
