In a double boiler melt your chocolate chips over low heat.
While the chocolate is melting, rinse and dry strawberries. Dip strawberries 3/4 of the way into chocolate and set to dry on a piece of parchment paper. Allow to harden completely.
Melt the white chocolate in a small microwave safe bowl for 15 seconds at a time, stirring in between each microwave. Drizzle over the hardened semi sweet chocolate on the strawberries in patterns and designs. Keep in the fridge for up to 3 days.
