When I first started with Warhammer, and painting miniatures, I found this video series by MniWargamerJay (go subscribe to his channel a lot of great information) and found this to be an amazing series for beginners, or just to brush up on some techniques. I am hoping to begin posting more video resources like this in the future that I have found that are/were really helpful for me, and might help you when looking for things to aid in your hobby endeavors.

Enjoy
