Used OO, CO, PO and Caster. I left most of the base natural color and then did a in pot swirl of brown. I ground up some oatmeal that I was going to add to the batter, but, my 8 year old was watching me and asking all sorts of questions and I forgot to add it. So, I ended up adding a some of it on the top of the soap, along with some whole piece of oatmeal. Smells yummy, but, doesn't look how I wanted, we'll see the final outcome after it's cut later today.
