How to draw a marker in an unmarked sketch book?

It's really hard to render a marker without a mark on the sketch paper. I've had similar troubles before. If you want to get better results, I can only suggest that you try using a marker pen or special marking paper.

Using special paper for markers will have better water absorption and thickness, but it is more expensive. Suitable for environmental art and other designs, not for animation.

Use thinner base paper, sketch paper, high-quality printing paper, etc. Suitable for drawing cartoons.

You can also use non-absorbent sulfuric acid paper and ordinary printing paper, drawing both water absorption and non-water absorption, two effects. Ordinary people can use printing paper. It's best to draw the back with printing paper.

Oily ink is more irritating and volatile because it contains oil essence. If the paint falls off the toy, you can use a marker to make up the color.
