Let me introduce you my two little boys,
Peter, was born on July 2005, he started to paint with watercolors on April 2010 at age of 5. After that he likes to paint everyday! On Jan 2011 began to use acrylics as well and he loves to mixes the colors.
Kimon, was born on May 2007, he started to paint with watercolors at age of 3. Thrilled when I saw him use the brush for the first time and creates that. Using a pencil he just doing circles, like others child's of his age, but he is handling the brush skillfully. About acrylics, he Impressed when he saw that mixing the blue with red, purple is made, magic!
