Cut your soap base into small chunks and place in a microwave-safe container. A little soap base goes a long way, so I started with about 1 pound of soap and added more if needed to fill my yogurt cups. Microwave the soap in 30 second intervals until it is completely melted.
Once your soap has melted, add 10 - 15 drops of each of the essential oils and stir with a plastic spoon or popsicle stick.
Prep your empty Jello box by punching a small hole in the unopened end with a sharp knife.
Fold the rope in half and feed the folded end up through the hole. Tie the loose ends together.
Place the Jello box on the cooling rack with a piece of parchment paper underneath. Pour the melted soap base into the box (it will drip a bit, but not too much!) and use a clothespin to hold the rope in place. Sprinkle with dried chamomile flowers (optional).
Let cool for about 2 hours before slowly peeling off the box.
Notes
After using your soap, put it somewhere it can dry when not in use, otherwise the rope may mildew.
