She is destined to become the world's youngest tattoo maker after learning from her dad, Blane, who runs a tattoo parlor in Wales.
Ruby will get a mini tattoo equipment for its fourth birthday in October.
Mr Dickinson told the North Wales Pioneer: "Ruby is very aware he grew older, he can not wait. He wants to become a tattoo artist when she grows up.
"The goal is to get a tattoo on my foot with a birthday message for my 40th birthday."
She took lessons after seeding and practiced with her father's appliance store toys.
Mr. Dickinson wished to defeat Emilie Darrigade record, a Canadian, who tattoos the arm of her father from a butterfly when she was five years old.
According to her father, Ruby is almost able to make her father's favorite design, which is a spider.
"I can not imagine that he'll use the Van Gogh, when he was only 3 years old," Mr Dickinson told The Sun.
"But I've got 70 percent of my body was covered in tattoos and will only be a 2p piece size, so I'm not too worried that she will make the tattoo."
Mr Dickinson, who runs Inkaholics Anonymous at his home in Penmaenmawr, Conwy, adding: "This will be a proud moment and very special for me and for their children.
However, despite hopes will take Ruby tattoo artist as a career, his father let his doughter make their own choices.. Sorry My English Is Bad.
