Laura Harm’s latest Zentangle challenge is up on her website.
For this tangle, I decided to use a Tachikawa School G Pen for Manga I got from JetPens.com. It’s a flexible nib, with cartridge filling system. I like that it’s able to give really fine lines. The nib flexibility gives the lines character. It’s definitely easier to use than a dip pen. The drawback is that you must use the pen every few days or the ink will dry up and clog it.
