This past week we made our own laundry soap. I remember making soap when I was little with my Grandma (except we used ivory soap instead of the Fels Naptha). It's super easy and quick - even Dominic helped.
I used this recipe. And I only spent about $6 on the supplies and easily have enough for 4-5 batches of soap. It works well so far and it's very eco-friendly.
