I've been meaning to learn how to do this for ages but was always too daunted by the learning curve. So today I took some time out of my busy schedule and went through Jake's class.
This is my initial sketch, that I then redrew in Illustrator and copied over to After Effects which was quite tricky, but got there in the end.
I had to find an external video to help me with the stroke start and end animation, as this is the effect I really wanted to achieve.
Great instruction from Jake.
Here is the final animation. (If it doesn't show you can see it on my Instagram feed: https://instagram.com/p/4o3WmZrcnr/)
