Cut about 3 ounces or 1/5th of the white soap into small uniform pieces and place it in the small heat-safe container. Melt in the microwave on 10 second bursts, stirring between each one.

Spritz the mold cavities with alcohol. Using droppers, carefully pipe the white soap into the citrus pattern. Spritz with alcohol again to pop bubbles. Set the leftover soap aside. If there’s white soap outside the pattern, remove it with a toothpic

Cut half of the block of clear soap base into small uniform pieces and place it in one of the medium heat-safe containers. Melt in the microwave on 30 second bursts, stirring between each one. Add 8 mL of fragrance oil and stir well.

Add a small chunk of either the yellow or green color block to each container. Stir to fully incorporate.

When the colored soap starts to cool and thicken (125-130° F), spritz the white details with alcohol and carefully pour the colored soap in. Spritz with alcohol again to pop bubbles. Let the soap harden for at least 4-6 hours. 

Carefully unmold each soap, being sure not to tear the white details. Once your mold is empty, you can repeat the above steps to make another pair of soaps. You will need to reheat the 3 oz of white soap before piping in the details. 

You will have enough white soap left over to make four more pastel soaps. These will look different from the bars made with clear soap, but they’re still just as cute! Alternatively, you can save the rest of the white soap for another project.
