In a large bowl, combine baking soda, cornstarch, citric acid and epsom salt. Divide mixture into three bowls and add pigment powder to each one. You will only need a small amount of pigment powder (about 1 teaspoon). The more pigment you add the more vibrant the color will be.

Combine melted coconut oil and lavender essential oil. Evenly distribute between the three bowls. Mix until well combined.

Spray a couple pumps of witch hazel to each mixture until it can form it's shape.

Layer the mixture into the mold and let dry for 4 hours or overnight.

Carefully remove from mold and spray with rubbing alcohol then sprinkle cosmetic glitter.
