I have been trying to draw the kind of folds. There are seven kind of folds.
- Pipe fold.
- Zigzag fold.
- Spiral fold.
- Half-lock fold.
- Diaper fold.
- Drop fold.
- Inert fold.
I have tried to make a sleeve, and capture in drawing for several kinds of folds such as half-lock, spiral and zigzag folds. Learn to draw will need continues practice, hopefully I can do this.
As a note : I made several edit on my drawing, to get more contrast because the real drawing is softener. As you can see below.
