I just made a basic 2lb batch of OO and CO, added China Rain scent, made my lovely swirls, poured into a loaf mold, went to go clean up, and I found my dish with the 2 tbsp castor oil. I was SUPPOSED to add at trace, but forgot.....bummed. Well, this is my 1st batch I have messed up (out of 4, whipppee), and its only 2lbs, still learning. Now what......It won't have much lather will it. Might smell nice, but wont give much lather. Tomorrows another day!
