1. Cut the soap into a slice that's bigger than the shamrock template.
2. Print and cut out the template. Trace the shape of the shamrock onto the soap.
3. Using a carving knife, cut the soap to the shape of the shamrock. Holding the carving knife at a right angle to the soap, cut four straight lines between the leaves and the stem with the knife point.
4. Cut a straight line in the middle of each leaf, and cut two curved lines in each leaf in a heart shape. Cut off the soap between the right and left leaves to create the stem. Done!
