Clean Line Art in Procreate: Brushes, Settings, Technique

Wobbly line art has three separate causes, and most tutorials only ever fix one of them. There's the brush (a settings problem), the hand (a control problem), and the screen itself (a hardware problem). Freya's Portrait Academy tackles all three before a single portrait gets inked, and her line lessons are worth reading even if you never draw a face.

Fix one: StreamLine, the smoothing setting

Procreate can smooth your strokes for you. The setting is called StreamLine, and it lives inside each brush.

Duplicate the brush first so you keep the original, then open it, go to Stroke Path, and raise the StreamLine slider. Freya sets hers to about 50% and the difference is immediate: freehand curves come out smooth instead of wavy. She recommends it especially for inking long hair lines.

There's a trade-off, and she names it. The higher you push StreamLine, the harder it becomes to draw tight curves, because Procreate keeps pulling the stroke straight. Her suggestion is to make yourself levels: duplicate the brush a few times with different StreamLine amounts and switch depending on the job. If you ever want the factory version back, About This Brush has a reset.

Fix two: your other hand

Try drawing a long line with your drawing hand floating above the screen. For most people it wobbles badly. Freya admits that even after more than ten years of drawing, floating lines are hard for her to control too.

Her fix comes from traditional painting. Rest your non-drawing hand lightly on the screen and let it act as a pivot, the way canvas painters rest a hand on the wooden frame while the fingers guide the brush. Don't press, just place it. For a long stroke, slide that hand along as the line travels. Weight goes into the resting hand, control goes into the fingers.

Resting a palm on a touchscreen normally leaves stray dots on your canvas, so change one preference: go to Actions, Prefs, Gesture controls, General and turn on the option that disables touch drawing. With that on, only the Pencil paints, and you can plant your hand with zero worry.

Two more control habits from the same lessons: zoom in, because a zoomed-in stroke is a steadier stroke, and rotate the canvas freely until the curve you're drawing sits at an angle your wrist likes. Freya turns her canvas constantly and points out she did the same with paper for years.

Fix three: the screen surface

Glass is slippery, and slippery is wobbly. Freya draws on a matte paper-texture screen film and is upfront that she can't work without one: it gives the Pencil the drag of real paper, which makes every line easier to steer. She's equally upfront that she sells her own film, that it wears the Pencil nib faster, and that some artists prefer bare glass. Her actual advice is just to try a matte film and see whether your lines improve. For many people this one change does more than any setting.

The exercise: trace, press, let go

In the Line Drawing Exercise chapter, Freya hands you a worksheet of lines and dots and asks you to trace them with the Freya Inking Pen Sharp (the regular Technical Pen works too). The rules are simple: trace the line steadily, and when you reach a dot, press harder so the line swells, then ease off. Sharp tapered ends, the kind you want for eyelashes and hair, come from letting go gently while the stroke is still moving. Lift abruptly and the end turns blunt and bloated.

What makes this exercise honest is that Freya does it on camera for the first time herself, wobbles included, and laughs about it. She also bans the crutch you'd reach for:

"But don't expect to be able to draw a perfectly straight line. Because those lines are not drawn freehand. We are drawing freehand. It will not be as perfect as a line from a computer. If we can draw freehand without too many waves or mistakes, I think it's ok."

No QuickShape hold-to-straighten during practice. The point is training pressure control so that thick-to-thin variation happens in one stroke, because going back over a line to thicken it is much harder to keep clean.

What clean inking looks like on a real drawing

The techniques come together in a portrait inking lesson from Freya's Create Anything in Procreate course, where she inks a little boy's portrait over a rough draft layer.

The workflow: sketch loosely on a Draft layer with the Peppermint brush, drop that layer's opacity, then ink on a fresh layer above it with the Freya Inking Pen Sharp. For the faintest lines, the nose and lips, she switches to the Super Sharp brush and barely touches the screen.

Two decisions in that lesson matter more than any brush choice.

First, fewer lines read softer. A child's face gets almost no lines at all, because every extra stroke adds years and hardness. Freya catches herself mid-lesson wanting to add more hair strands and stops: "Sometimes I need to stop myself too." Clean line art is as much about the lines you leave out.

Second, hair is drawn with open lines, strokes that don't close into outlines, so the coloring can flow out of them later. Locked, closed outlines make hair look like a helmet.

One clever exception to the no-QuickShape rule: for the irises, she draws a circle, holds, and taps with her other hand to snap it into a perfect circle, then erases the part hidden by the eyelid. Practice freehand, but use the tool when a shape genuinely must be geometric.

Putting it in order

If your line art is messy today, work the fixes in this order: turn on the palm-touch preference and start resting your hand (free, instant), raise StreamLine to around 50% on a duplicated inking brush (free, two minutes), do the press-and-release tracing drill until tapers come out sharp (a warm-up, not a one-off), and try a matte screen film if glass still fights you.

The tracing worksheet and both line-control chapters are part of Freya's Portrait Academy, which goes from these drills to full drafted, traced and colored portraits. A few of its lessons are free to watch if you want to see her hand placement and pressure on video rather than in words.
