Preparation for a mirror frame starts with a red paint base for gold leaf application. The molding is progressing well, with about 30 hours of work remaining. After sanding damage, repairs are made to the main mold, and the base coat dries before gold leaf is added. Cleaning surfaces is crucial, using an improvised toothbrush, while managing dust from plaster removal is a concern. Wall removal is also necessary to ensure a level and square structure for tiling.
