***sigh***
I bring you yet another lesson in what not to do...
Never use felt markers with dip pen ink, even if that ink is NOT water soluble. The Marker ink just melts the dip pen ink. I guess one could use the dip pen ink if they do the black lines last... I also have not tried using acrylic ink, it may stand up better to felt markers...
I may redo this piece because I quite fond of the pencil, but as for now I just stop before it was finished... too ruined.
BTW... the rating is "G"
