The Magnetic Sketch Board is one of my son's favourite. This is how he practices his strokes. It is environmentally friendlier than paper. However, you can't keep works like you do with paper, so I take pictures of them.

My Dad just built the fence. It was my son's first time noticing the Cactus that Mom grows in the garden. The millipede looks more like a snake..but it's cute!
