While doing the class with Judy Coats Perez at IQF, one of the things that we discussed was a ruling pen. It is a pen that, pre-computers, was used with mechanical drawing. Now that computers do most of the work, they are hard to come by.
Well, I found something similar in Michael's! It is called a Fine Line Painting Pen by Lowe-Cornell, Inc. I found it in the section where they sell the inks.
This is a close up of the nib.
And here is a picture of what it looked like when I was drawing.
I had to thin the paint just a little with a bit of water but once I had it flowing, it worked beautiful.
I also tried using Tsukineko Inks. I like to experiment but there are no pictures as it was a disaster! It ran and would not give a smooth line. I also had a little bit of trouble getting the ink into the nib as I didn't have the little squeeze thing to do that with. I tried by using a syringe. Don't do it! It was a disaster.
On a related note, does anyone know how long it takes for red Tsukineko Ink to wash out of hair?
