Lavender is an ingredient with myriad therapeutic benefits: it's known to relieve stress and insomnia, as well as soothe the skin. This soap-making project uses an easy melt-and-pour technique, calling for three all-natural ingredients: goat's milk, lavender essential oil, and pink Himalayan salt-all of which combine to help you (or the lucky gift recipient) luxuriate at home.
Cut soap base into chunks and place in a large heatproof glass measuring cup. Heat in microwave for 30 seconds; stir. Repeat until smooth throughout. Mix in about 30 drops essential oil.
Sprinkle salt in bottom of mold. Pour in about 1/2 inch melted soap and let sit two minutes. Then sprinkle with another thin layer of salt and let sit five minutes. Repeat, adding 1/2-inch layers, until you reach the top of the mold, then sprinkle another thin layer of salt on top. (For a slightly thicker layer, spritz with water and then sprinkle on more salt.) Let set several hours.
Gently peel away sides of mold to release block of soap onto a cutting board. Using a bench scraper or sharp knife, cut soap into 1-inch-thick bars (if needed, heat blade over a burner to facilitate cutting). Optional: If gift-giving, wrap bars in kraft paper and tie with twine.
