A coworker gifted me with the awesome flower shaped mold that is intended for use as a bread pan. She suggested that I could use it as a soap mold and doesn't care if it is ruined IF I will teach her to make soap. It measures about 3.5" across and would make a great upright mold. Problem is how to line it. Freezer paper is out because of the contours. Would plastic "cling wrap" work, or would the lye dissolve it? What are your thoughts or advice? Pic is below. Thanks
