Lesson 3: Applying Construction to Plants
Daisy Demo
Demo Video
Here we look at tackling a flower, using the principles of leaf construction and applying them to a different, but similar form that follows the same principles of being flat and following the flow of external forces.
The demo video includes full audio and discussion of the concepts demonstrated in the drawing.
Step by step
We start out with just a few marks. First we want to establish the path the stem is going to follow, and ultimately how it connects to the head of the flower. We've done this with a flowing line (the arrow coming down and to the right), and a couple of contour ellipses to start establishing the base of the flower's head.
Applying the branch construction technique covered earlier in the lesson, we draw a stem along the path we established in the previous step.
Remember that in order to maintain control over this longer curve, we're building it up in segments that go from one ellipse past the next. As we lift our pen, we aim that stroke towards the ellipse that follows. The goal here is to have each segment we construct overlap the previous one, causing them to blend smoothly into a continuous stroke.
We've also added a bit of a hemisphere or dome form to help build out the core from which all the petals flow.
For each individual petal, we've constructed a separate "flow" line, as covered in the leaf construction exercise. While these are petals, and not leaves, the same principle applies because both are relatively flat and as such are heavily impacted by the flow of wind and air currents that surround them. You'd apply the same tactic to any such object or form.
Make sure you're drawing each flowing line with confidence and with consideration for how those forces are going to be pushing on your leaf. Don't draw shallow, stiff lines - take your time, apply the ghosting method, and don't half-ass it. The flow line is the core that defines the behaviour of each leaf or petal.
Again, following the leaf construction method, enclose the flow line from tip to tip with two edges, creating the overall shape of the petal. Do your best to have the petal end where the flow line does, and push through those lines with confidence again.
Don't be afraid to let the petals fold back on themselves. All we're doing is guiding lines that flow through space.
Now the petals on this flower are pretty simple, but if you ever need to add any edge detail like wavy, fraying or spiky edges, avoid the following:
-
Zigzagging your lines, each deviation from the previous phase of construction should be drawn as a separate stroke, maintaining the basic mark making rule of each stroke maintaining only a single trajectory.
-
Ignoring the initial enclosing edge of the shape - your details should always come off that initial edge and then return to it.
-
Working subtractively - don't cut back into your basic leaf shape, or any form if you can help it. Work additively, always attaching new forms to those you've already established in space. Subtractive construction, while a viable option, usually requires far more spatial awareness of both the form already on the page and the piece you're cutting away, and it's very easy just to think about them as they exist in 2D, thus flattening out your drawing.
We finish off this drawing with a bit of detail here and there. Notice that while there are many lines running lengthwise along the petals (which you can see in the reference image as well), each one should be drawn with care, to follow the same flow of the petal itself. I'm also allowing these strokes to taper a lot more, by applying much less pressure, though the confidence of the stroke is still more important. If you aren't mindful of each stroke that rests on a surface in your drawing, you risk contradicting the construction you've already laid down.
Faber Castell PITT Artist Pens
Like the Staedtlers, these also come in a set of multiple weights - the ones we use are F. One useful thing in these sets however (if you can't find the pens individually) is that some of the sets come with a brush pen (the B size). These can be helpful in filling out big black areas.
Still, I'd recommend buying these in person if you can, at a proper art supply store. They'll generally let you buy them individually, and also test them out beforehand to weed out any duds.
