They are available at www.utales.com. There is also an iphone and ipad app available on itunes. Paloma's Pie is written by my collaborating author Jean Heilprin Diehl.
I did all the illustrations on an ipad using Sketchbook Pro. I included sounds and animation in The Princess on the Pea and The Baker Dog, by utilizing the utales tools.
