Hello I have tried to make my first melt and pour soap. 1. Shea butter base with dried lavender - the soap is lovely but after using it in the shower, the lavender flowers seem to have left brown stains. Is that normal? Do we use preservatives in a melt and pour soap? 2. Honey and oatmeal - I mixed oatmeal in a clear base and honey on top. However, the honey did not stick to the soap base. How can I get the honey to stick on and show as a separate layer?
