By preschool do you mean 4 year olds? I taught preschool for 17 years and
would be glad to give you some advice.
Keep it simple and concentrate on sensory projects. Tearing, cutting, drawing
and painting skills should be emphasized. I use story books a lot with my
kinders and also did with my preschoolers.
Concentrate on colors, shapes, textures at first. Artworks with animals with
hold thier attention.
Attention span is VERY short so keep it simple. Good luck, Janet
