Essential oils of choice (I used about 20 drops of lemon-eucalyptus)
Method
Place all ingredients except essential oils in a quart mason jar. Bring a stock pot full of water to a boil with the uncapped jar sitting inside. Stir regularly until all ingredients melt completely.
Let cool slightly. Add oils and stir. Pour into silicone molds like these I found: daisies silicone mold and snowflakes silicone mold.
Let set completely (overnight is best). Pop out of the molds and place in mason jars, decorate and tag accordingly.
