Q
This isn't a challenge, it's a question: how do you draw your robots? On paper with color pens and then someone scans them into the computer? Or do you have another way? Thank you for answering.
A

I put them on paper and my dad scans them. I help. The markers are color-changing markers. You put the color on, and then you put the chemical on upside down and the color changes. I like the color-changing markers.
