Hi everyone !
I've wanted to start making tutorials again for a while. However, writing a complete tutorial (and putting it together with a painting software :XD: ) demands me a lot of time... So I've decided to do something simpler by dividing my tutorial ideas into smaller parts and writing them as journals instead :)

The Basic Types of Folds

Almost two years ago, I've published a series of sketches on folds, which were the result of my current studies on the subject. I've recently started to study drapery and fabric again, so I've wanted to share my latest and up-to-date thoughts on this with you ^^

There will also be some general advice and tips on drawing.

I - The Diaper Folds

Here is the final drawing I will decompose in this tutorial :

Diaper Fold - Final by Aliciane

1. Definition

A diaper fold is created by the slacking of fabric between two points of tension. Schematically, this is what you should have in mind when you start sketching this kind of fold :

Diaper Fold - Schematic by Aliciane

Notice that all main folds radiate from the tension points.
Some parts of the fabric are only connected to one of the points. Because of gravity, they fall straight to the ground and create pipe folds. I won't enter into details about those here, but they are pretty simple, so don't worry too much about them :)
The parts of the fabric which are connected to both tension points bend into diaper folds. The gravity pulls the fabric down, creating a concave upward curve between the two points.

2. General rules for sketching

Now this only gives you a general idea of the position and the direction of the folds. To go one step further, I'll give you some insight about what I think when I sketch folds. These tips are pretty generic, so most of them can in fact be applied to sketching any object.

For me, the aim of a sketch is to establish the structure and to start suggesting the volume of an object. Therefore, I want it to be simple, clear and confident, in order to create a sense of solidity. Here is the sketch I made for this drawing :

Diaper Fold - Sketch by Aliciane

Rule 1 : Keep your strokes simples

Diaper Fold - Sketch (Rule 1) by Aliciane

Ideally, you should mainly use straight lines ('I'), curved lines ('C') and exceptionally something as complex as a 'S' line when needed. Avoid unnecessary convoluted lines; make your strokes fluid, confident, and draw them in a single motion when possible.
Curved lines can be broken down into separate sections if appropriate, like the teal line in my example. But keep in mind that you want to simplify your subject, and avoid being caught by all the tiny bumps or creases there might be. Look for the main shapes.

Rule 2 : Keep your shapes varied

Diaper Fold - Sketch (Rule 2) by Aliciane

Try not to make all your shapes with the same width or the same length. Have short strokes, long strokes, large folds, narrow folds... Using too similar shapes can quickly give an artificial and amateurish look to your drawings. This is also true for clouds, trees, locks of hair...
But you actually don't need to make it excessively varied. Simply thinking of your shapes as either big, medium or small is usually enough to trick the eye into seeing a satisfying and natural amount of diversity :)

Rule 3 : Keep your lines meaningful

Diaper Fold - Sketch (Rule 3) by Aliciane

This is actually the principle that helped me the most for drawing folds. Constructions lines have a meaning and a purpose. They are here to define the contour and the various planes of an object. Therefore, floating lines starting or ending for no reason make no actual sense. It is ambiguous and it will confuse you when it'll come to shading your drawing.

A line can only end (or begin) in one of the following cases : if it is overlapped ('O') by another line, if it merges with another line at a tangent ('T') or if it meets another line at a corner ('C'). You shapes should be closed; an open shape does not make sense in terms of planes and volume.
Lines represent edges. Those edges can present different qualities, from hard to lost, and should ultimately be rendered as such. Usually when we ink a drawing, the softer edges are implied and only the harder edges are represented as lines, as shown here :

Diaper Fold - Inking by Aliciane

But in the earliest stages, I encourage you to mark all the edges as lines, regardless of their quality. It will force you to see those planes and to acknowledge the existence of soft edges and changes of orientation that you would otherwise maybe overlook.

Rule 4 : Keep the folds' directions

Diaper Fold - Sketch (Rule 4) by Aliciane

If you continue the lines which have been interrupted, they should follow the same principles as the visible lines. All the folds should converge toward the tension points, whether you can actually see them or not. Try to see through your drawing and to visualize your lines in their entirety. Do not hesitate to actually draw them if it helps you !

3. General Rules for shading

With a good preliminary sketch, shading (or painting in colors) should be easier. For me it is, and this is why I often spend a good amount of my time planning, drawing, constructing and such. Here are some additional tips to make the transition to values easier :)

Rule 1 : Think about the volume

Diaper Fold - Shading (Rule 1) by Aliciane

Take some time to analyze your drawing and to ask yourself if you can visualize the volumes of the various parts of your drawing. Remember that any complex shape can be regarded as made of basic shapes. In draperies, there rarely is any planar nor spherical surface, so everything can be considered a part of a cylinder or a cone. Don't hesitate to draw cross sections lines, like I did, if it helps you see better. See how the construction lines come in handy to suggest the volume.

Rule 2 : Think about the light source

Decide on the position of your light source and stick with it ! You don't have to be extremely accurate in your shadow placement as long as it seems roughly consistent. Here I imagined my light source would be at the top left of my drawing. Therefore core shadows will mainly be located on the bottom right of my shapes while cast shadows will likely appear on their top left.

Rule 3 : Think about the type of shadows

You may have felt lost when I mentioned 'core' and 'cast' shadows.

Basically, a core shadow is a shadow that is related to the form of an object. The planes perpendicular to the direction of the light receive the highest amount of light, and as the planes turn away from the light, they get gradually darker, until they don't receive any light. So that is why the parts oriented toward the light direction (top left) would be light, and the parts opposite (bottom right) would be in shadow.
Now an object can also get in shadow because something is preventing the light from reaching it. Each object projects its own shadow. Therefore, if a fold is located under another fold, the top fold will cast a shadow on the bottom fold, thus obscuring the top of the bottom fold (is that clear ? :XD: )

Diaper Fold - Shading (Rule 3) by Aliciane

I have a few tips regarding how to render those types of shadows. First, make the cast shadows darker (we'll see why just the section after). Second, forget about the shape that is casting the shadow. It does affect the shape of the shadow, but it is way too complicated to be really taken into account when drawing from imagination. Instead, make the cast shadow follow the shape it is cast on. It will help better show the volume and the result will be accurate enough. Finally, cast shadows usually have harder edges than core shadows.

Rule 4 : Think about reflected lights

Diaper Fold - Shading (Rule 4) by Aliciane

The darkest area of a core shadow is usually where it starts. It corresponds to the area that is tangent to the light direction and it is called the terminator. I've shown you one in orange. The rest of the core shadow is usually slightly lighter because of the light that bounces off lit surfaces (as shown by orange arrows). It can take many names : indirect lighting, reflected light, bounced light... All means the same actually. So try adding this slight gradation to your shadows and see how it looks !
Finally, some places I've indicated by teal arrows will be fairly light if the fabric is thin, because of the light passing through it :)

And that's it ! Damn, that was longer than I expected, I definitely don't know how to make something short. Hope you'll find something useful in that mess, and happy fold studies :D
