I Can't Draw is a digital book that teaches the fundamentals of using Grease Pencil for 2D drawing and animation within Blender's 3D environment. The book is structured into two main sections: a theoretical overview and a practical guide.

The theoretical section introduces Grease Pencil concepts and explains how to utilize it effectively. The practical section guides readers through creating and animating a 2D VFX impact effect. While the tutorials are based in Blender, the foundational drawing techniques can be applied to other digital drawing applications like Procreate.
