Very slowly add wet mixture to dry ingredients, and mix well. You may notice some fizzing - just keep stirring. (Note: Don't dump the entire wet mixture at once as it will activate the baking soda and citric acid. It's important to stir it in very slowly.)
Test mixture. You should be able to clump it together to mold. It shouldn't be too wet or too dry. If it's too dry, add 1 tsp of almond oil as needed.
Optional: Add dried lavender flowers to bottom of molds.
