A ten - fifteen minute intro via You Tube and I was playing about.
I'd recommend the Apple Pencil above other styli as it responds in a similar manner to a Wacom Tablet, pressure angle etc.
I'm not planing on taking the iPad out on a Sketch Crawl, I'll stick to pencil, paper and water colour as they are easier (& far cheaper) to replace.
Nice! I don't have the procreate app ( we have an iPad pro at work) I've tried the Adobe sketch app and I thought the watercolor was really fun to use. Simulates bleeding and pools as well.
