How to make deep folds

Hello everyone!
It's Vili here today and I want to show you my way of making deep contrasting folds.
As you've may already noticed I use from really dark to really light shades. I colour pretty confidently without worrying for the final result.

I chose Mo's Alisa With Roses because her dress is suitable for my aims. I coloured the skin. the hair and the basket beforehand and now I'm starting with the detailed explanations:

I'm thinking of making the dress in the pink-purple range so I chose these colours:

 
I always start with the lightest colour in order to 'wet' the place I'm colouring:

After that I mark the places where the folds are with the darkest colour: 

I continue with a lighter tone:

And a lighter one:

With the lightest colour I fill the most protruding sections:

If I think a place should become lighter, I slightly touch it with the Colorless Blender. These are mostly the sectors with many folds, like the one around the waist: 

After I have finished colouring the picture I put a contour. Here I don't mind about the direction of light and don't look for the places with the most thick shadows. I try to make the picture look more contrasting on the main background. I place contour all around the image:

I  put in some darker tones:

Then comes a careful 'washing' of the two colours with the lightest grey:

And the picture is ready:

And this is the card which I made with this image:

Have a lovely day and thanks for stopping by!
