Proud Grandma alert!! My young grandson, Andrew, aged 5, saw the picture I made with my tree stamp and Brusho paints (see here) and he wanted to make one.
First he punched a circle from a post-it note to make a mask for the moon. Next he made the Brusho background by dipping a paintbrush into the powders and tapping it over the paper where he wanted the colour. Then he sprayed water over the picture until the colours had merged to his satisfaction. He did all of that with instruction but no physical help.
Having finished his background, he compared it with mine and decided that my picture was too plain, as it only has the tree and a bird. We looked through my stamps, and he found the Hobbit Door (Lavinia Stamps) and said that he wanted his to be a picture of The Shire (from Lord of the Rings. He's a big LOTR fan!) He chose some other stamps to go with the Hobbit Door (from Lavinia, Inkylicious & Hobby Art) and decided where they all should go. I helped him to hold the stamps as he was stamping them, just to make sure that he didn't smudge the images, because it would have been a shame to spoil his lovely background, but everything else was entirely his own work. He finished by colouring the door surround and the tree with coloured pencils.
We both decided that his artwork was far superior to mine!
