Flowers are NOT easy to draw!

Well-executed flower pen-drawings are a hit on some social networks and therefore shared, liked and commented on.

I hope that by the end of this flower-drawing guide, you will be able to draw your favorite flower.

You can use a real flower as reference or an image of a flower.

Concept Art

First thing first, do not use concept images that are protected by copyright law.

What will happen if someone likes your beautiful drawing and wants to buy it?

Therefore, make it a habit to use images that are free for ANY use.

Here are some websites that let you download FREE stock images.




How to Create Smooth Lines with a Pen

For a pen drawing to look nice, each mark should be drawn with confidence. Meaning, a smooth line.

That is easier said than done!

With time and practice, the lines will flow. Until then, we will start with a pencil.

The advantage of a pencil is that it is erasable. Therefore, we can fix mistakes until we are happy with the result.

So grab your reference image and draw it with a pencil. Draw it gently so it will be easy to erase later.


The pencil drawing does not have to be perfect. Remember that nature is abstract. There are no two flowers that are the same.

Once the pencil-sketch is ready, it is easy to go over it with a pen. Do it in a confident and smooth way, even if the pen marks are not exactly on top of the pencil marks.

When drawing with a pen it is important to pay attention to overlap.

Parts that are closer to the observer should be drawn first. In this case, draw the stamens first and only then draw the petals.

After the ink from the pen is dry (usually in few seconds, depending on the pen brand), it is safe to gently erase the pencil-drawing marks.

How to Draw a Complex Flower

Some flowers or compositions are quite complex and attention should be paid for proportions, foreshortening and perspective.

This is too much to deal with when starting to draw.

A solution to this problem is to create a grid of guidelines. Then, instead of one complex image, we have several smaller and simpler images.

To find the middle point of an image, draw two diagonal lines from the image corners.

Now we can draw horizontal and vertical lines from the midpoint.

Do the same for the drawing-paper. Make sure the ratio between height and width is the same for both the reference image and the drawing-paper.

You can crop the reference image to get the same ratio.

Now it is easier to draw with a pencil.


If the image is still complex for you, you can keep adding grid lines for each square.

Remember to use the pencil gently. It will be easier to erase after you draw with a pen.

Which Pen to Use for Drawing Flowers

While it is possible to draw or sketch with a regular pen, there are many advantages for using pens for artists.

These pens are called fineliners or technical pens and their ink is usually black though some brands offer additional colors.

Pens for artists create lines of uniform thickness and they come in different sizes, therefore enabling to draw thick contour lines or thin lines for details.

The ink for these pens is made of pigments and therefore very durable.

Line Width & Size

When drawing with a pencil, we can draw soft edges for far away objects.

Pens have one brightness value and therefore cannot produce soft edges.

Instead, we can use a pen with a smaller nib size to create thinner lines for background objects and bigger nib size to create thicker lines for foreground objects.

Using different nib sizes to draw flowers Different nib sizes

Using lines with different thickness to add depth:

Another way to add depth is with size.

When drawing in perspective, the farther away an object is, the smaller it will look.

For that reason, flowers in the foreground will be drawn bigger while background flowers will be smaller.

To add depth to your drawing, create the background flower smaller, use a pen with smaller nib size for it and make the foreground flower overlap it.

Hatching and Crosshatching

Hatching is a drawing technique that uses parallel lines.

A pen produces lines with one (dark) brightness value.

In order to create the illusion of different brightness values, meaning areas that look lighter and areas that look darker, different types of hatching can be used.

Thin hatching lines can be used for light areas.

By using different degrees of crosshatching, it is possible to create the illusion of different brightness values:

After some practice with drawing flowers using pens, it becomes quite fun and relatively fast to produce.
