Once having learned how to draw jeans it is natural a “ how to draw denim tutorial” to follow. Here you will learn how to recreate denim fabric in your fashion illustrations using a very quick and easy technique. Step by step, as always!
Step 1: Base color
Including all the details, draw the garment you want to make look like it’s made of denim. Denim clothes are usually stiff and when you draw the folds make sure they don’t look too soft.
Lay down the first layer of color. The final version of the jacket will get much darker, so pick a light blue for base.
Step 2: Shadows
Draw the shadows using a second layer of the same color or a slightly darker shade. Normally the clothes create shadows where there are creases or one surface is in front of another ( see the pocket). Also notice how the color of the collar changes in depth. The same happens with the sleeve.
Step 3: Add some texture
Start adding narrowed lines all over the fabric. Make sure that the lines look organized and follow the same direction. It is best to use a color pencil in a very similar shade to the base color.
Step 4: Even more texture
In the places where there are shadows repeat the process, but using black/dark grey color pencil. For the places you think are brighter use a white pencil.
Try not to overwork your drawing with black and white lines. If you do so, erase the unnecessary ones.
Step 5: A realistic denim fabric
Take your white pencil again and this time make strong vertical bleached effects. They are supposed to hint where the jeans clothes are worn-out. Put those only where the volume of the body is the most bulged.
Step 6: Add some details to those clothes
Find an orange or brownish shade that will overlay the base color of the jeans and underline the stiches.This is very specific for jeans. Color the buttons and if you have any other details.
Step 7: Smoother
You already have it done, but if the fabric looks too sharp for your taste I recommend you to take a paper blender and go over some parts of the sketch. This will give nice polished look of your fashion drawing.
Have fun experimenting with denim fabrics in your designs!
