Arrange 4 pecan halves in a cluster, flat side down on cookie sheet.
Repeat with the rest of the pecan halves.
Place one caramel on top of each cluster.
Heat in oven until caramels are softened, about 4-6 minutes.
Press caramels flat with the bottom of a buttered spatula (you may have to butter the spatula after every 2 or 3 caramels, or it will get very sticky).
Remove caramels evenly onto waxed paper.
Melt chocolate in double boiler, or in microwave on medium high, stirring every 25 seconds until just melted.
