Children's Art: Pattern Painting again

I know we did that before, but I wanted to repeat it with my little children painting group....

First we divided a piece of paper in fields using a pencil. The children painted each field in a different color using tempera colors.

After the work was completely dried they started to do the patterns.
This time we used Q-tips for the patterns and the children were asked to use different colors to overlay each field although I asked them to observe what happens if they cover to adjacent fields with the same pattern.

Here you see the results of our kids :-)
