Custom Breast Milk Soap

We all know how good breast milk is for our babes skin.  What better way to use up your freezer stash than to make it into soap?
 Here's how it works:
Choose your base:
Tallow $40
or
Shea $30
Optional add-ons:
Lavender essential oil $2
Oatmeal $2
I need 6 oz of your frozen breast milk. You'll get 4 bars of soap back, measuring 2.5" by 3.5". 
Store in the refrigerator until use. Once a soap bar is in use, make sure it dries completely in between uses in a well-draining soap dish. 
I recommend freezing any bars you won't be using within a couple months.
