My journey with penmanship is full of amazing people on this forum.
Here's a small tip bit:
Use gum of Arabic. I have shied away from using gum of Arabic for the longest time. I came from the fountain pen world, and uses ink designed for fountain pen use. For pointed pen, it worked well. FP inks worked fine with most nib and paper. However, it tends to feather and bleed thru. That is until recently, I added Arabic powder.
I have sampled with just copy paper, journals etc.... your ordinary paper. It worked very well. On premium papers will show better quality.
However, I have encountered too much hard start. My presumption is the nib is worn and also maybe too much Arabic powder was added.
