We recently repaired our textured plaster ceiling. We now want to duplicate the textured design in the repaired area. The design is that of plaster flowers (some type of brush or comb was used in a circular pattern). Does anyone know what type of tool to use to duplicate this design? We tried regular hosehold items such as plastic bags but these leave too detailed of an imprint. The local hardware shops only sell regular stipling brushes which would give the ceiling more of a popcorn look, which we don't want. Any ideas on how to do this?
