Hello! I'm Chou-Tac, a Product Designer from France.

If the sketching methods I’ve acquired aid me in my life and in my industrial design career, I believe that they can also help you reach your dream goal as a student or professional designer.

Want to add fresh textures to your sketches? Try drying your marker tip to achieve special line effects and varied thicknesses. Explore how simple marker prep can elevate your design drawings. Ready to experiment and transform your sketches? Start drying your marker now!

Today I’ve just get a set of 30 twin markers. The brand is TOUCHLIIT.
My friend gave me a warm recommendation of them. Let’s try them!

The sketches are done with the thick tip only.
Unfortunately I didn’t get the “Layout paper” for markers. Be aware that by using normal paper, more ink will be absorbed and kind of wasted.

These markers have double tip. One thin, one thick. The thick side is bevelled. That’s the common tool for any designer.


TIP 3 DRY YOUR MARKER

Test every single edge and corner of the thick tip. Each of them give a specific thickness and “dryness” to your lines. I personally like to take out the cap, and wait for a while. The tip will dry a bit and give you nice lines similar to regular pens.
