For the ink drawing, can I use a sharpie?
Can you use a fine point sharpie instead of the magic ink? Please , don't laugh I'll get this ink all over me, I just know it!
Sharpie brand ink pens have a type of ink that will repel the oil paint layer and bleed through the painting. There are several manufacturers that make a felt tip, fine point pens with "water proof India ink." They will be found in your local art supply store in the drawing section. At least, that's where I found mine! Stick with these if the calligraphy pen is gonna make a mess for you.
PS, most art stores have the water proof india ink in pre-loaded cartridges for calligraphy. try those instead of an ink well.
