It's been awhile since I played with my water soluble inks so I grabbed two of my pens that have different inks and worked these three quick wash sketches.
All worked in the Hand.book.
First is using the Rotring Art Pen with a "F" nib. As noted on the page, I had forgotten just how potent this ink is when water applied. Normally I would use a flat brush as I can better control the wash but I was working with a waterbrush with these sketches. Maybe using a smaller tipped waterbrush might have helped.
These next two pages is using one of my Pilot Prera fountain pens and Namiki Black ink. It's much more subtle and easier to control.
