Can you guess what’s in the image below?
3D-Hand

I created and colored one of my hands on the paper.

3D-Hand

If you would like to create your own 3D hand like mine with optical illusion, here’s what I did, I traced my hand and drew stripes like the ones in the picture above. Then I filled them with colors of my choice in a repetitive order. I used Crayola’s following¬† shades in sequence ¬†:
outrageous orange, red, blue green, cerulean, cerise, royal purple in a recurring order.
