I have worked on an Affinity Designer course targetting absolute beginners who have never done vector drawing before.
Currently, the course is on sale for $ 9.99. Please feel free to check it out at https://www.udemy.com/affinity-designer-vector-graphic-for-absolute-beginners/?couponCode=FORUMPOST
Alternatively, you can join my course at SKillShare (Get 2 months free): http://skl.sh/2oduIrs
Totally it has 4 hours of content and another 2hour of content is in post-production, so soon the course will have 6 hours worth of study materials.
More details about the course can be read on the link given above.
