My dip pen practices are improving slightly.
My biggest problem is that my eyes can't see what I'm supposed to be following. Or more to the point, I can't analyze what I'm looking at. This is the same problem I'm having with my
penmanship practice. I can trace the letters, but when it comes time to drawing them without a guide, I forget how they go. Very frustrating and I suspect related to my dyslexia and my slowness to learn to spell/write/read. It takes weeks dedicated to learning to spell each word and in school, they would 'teach' us 20 to 50 words a day. That was far too fast.
The next problem - ink feathering/bleeding. I switched from fountain pen ink to calligraphy ink (which feels more like paint, it's so thick) which has solved most of this problem. Maybe later, I'll get some better paper.
Today I tried something different since I'm 'writing' in 'paint', I decided to treat my nib more like a paintbrush. Instant improvement.
