First, I got a bar of ivory soap which is what we use (plus it is very high in Alkaline) and I grated it into a pot of water (1 pint of water to be exact).
Then I brought it to a boil, stirring constantly until all the soap pieces were melted.
TIP: for a more yummy smell, I also added 1 tablespoon of cinnamon and melted it along with the soap.
Next, I pour it into a clear mason jar and put it in the fridge for two hours.
Next, I made a hole in the top lid.
I had some fabric stored away, so I pulled some out and cut out a piece.
After placing it above the lid, I screwed the top on and inserted my empty bottle's pump into the hole I had made. PERFECT!
Not bad for my first go at it!
