How long to learn ~5-10 mins
How difficult to learn 1/10
Tips
1.) Start of slow and gradually speed up it won't look good at first but as you develop dexterity it will look better and more fluid at speed
2.) Try out different size pens, pencils or markers. Thicker ones may be more difficult to rotate between your fingers but most pens should do fine.
