wow thats alot of soap.. They look very nice too and the picture is fine. My batches are usually very small compared to yours. one of mine today was only 16 oz., the other 20 oz. I'm still in the experimenting and learning phase.
Heavy cream is what you buy in the grocery store in the dairy section by the milks. It's what is used to make whipped cream and other delish things. "heavy whipping cream" is what is on the label, it's the cream part of the milk after it's seperated.
