Susy also uses the ZIG WRITER MARKERS (not shown) for outlining, flourishes and monoline writing.  Each double ended Writer marker features two sizes of bullet tips (.5 and 1.2 mm) and is available in the same 48 colors listed for Zig Memory Calligraphy  markers. Susy often uses the darkest color of the three scroll & brush markers she is layering as the monoline accent color.
