My oldest daughter enjoys a variety of artistic endeavors. Some of her favorite expressions are heavily influenced by Asian, and more specifically Japanese, forms. These range from traditional watercolors to manga style characters, and is beginning to teach herself Kanji. I would like to get her a fountain pen and ink for her upcoming Birthday for inking her work and would appreciate suggestions. The process is first a rough pencil sketch that is then inked over, pencil lines are erased and then watercolors are are panted over. If she likes the finished piece than the work is sealed with a light spray similar to a varnish. The ink would have to be near bullet proof to withstand the process. I was thinking of a flex pen as that would give her greater line control and was impressed with the video I saw of the Ahab pen but have little FP experience and none with a flex nib. Any help or advise would be appreciated.
