I have been browsing the lessons and trying most of the exercices and I find myself to have one slightly annoying problem... When it comes to hatching, I go too fast. Especially when it comes to curved lines such as in: F08 - Basic Contour Hatching and F09 - Graduations with Contour Hatching.
When I make the curved lines, I sketch them quickly and fluently, but I don't seem to lift my pencil fast enough at the end of the line! As a result I sometimes end up with little hooks and curls at the end of my strokes.
Then I force myself to slow down, which helps a lot, but within a minute I zone out and slowly speed up again, untill I realise I'm doing it all over again.
Anyone have any remedies, tips or tricks? Other than practice, practice and more practice that is, cause I'm already working on that one
