Glycerine soap is fun and easy to make yourself. The soap base is sold at most craft stores, along with all sorts of colorants and scents and molds. Essential oils can also be used to scent the soap. Cut the soap base into small chunks and melt it in the microwave or over a double boiler. Add your desired colorant and scent, stir to mix, and pour into a mold. When it sets up firmly, remove it from the mold and enjoy!
