The Pens I Use in My Pattern Sketchbook

I often get questions on Instagram about the pens I use in my sketchbook.
Over time, I’ve found tools that support the way I like to work — intuitively, rhythmically, and without too much planning.

In my pattern sketchbook, I work almost exclusively with acrylic markers.

Why acrylic markers?

I’m drawn to acrylic markers because they offer a rare combination of qualities:

• they are odorless

• the paint is opaque and vibrant

• they dry quickly

• they don’t bleed through the paper

• and you can layer one color over another

Since I work in flat shapes rather than shading or blending, a fast-drying, covering color makes the process feel simple and fluid.

My favorite: Posca Markers

My go-to markers are Posca.

Most often, I use:

• PC-3M (bullet tip) — perfect for lines, shapes, and repetitive details

• PC-8K (chisel tip) — ideal for filling larger areas with color

They are not the cheapest option, but the paint quality is exceptional. The coverage is smooth, and the colors remain strong even when layered.

A budget-friendly alternative

Right now, I’m also testing acrylic markers from Shuttle Art with a soft brush tip.

They are more affordable and come in many beautiful colors. The paint isn’t quite as opaque as Posca, but they’re a lovely option if you want access to a wider color range without a large investment.

Why they work so well for sketchbook practice

Because I draw freehand, mistakes are part of the process. Acrylic markers are wonderfully forgiving — if a shape feels off, I can simply paint over it and continue.

This allows me to stay in the flow instead of stopping to correct or plan.

They also dry quickly, which means I can work intuitively and build shapes and rhythms without waiting.

A small tip for smoother color

Try to keep a steady paint flow while filling shapes.
Working with a pen that is too dry can cause streaks or make the paper surface pill.

A generous, even flow creates smoother color and a calmer drawing experience.
