How wonderful that you've been able to get this done. I also wrote a children's book and had a young lady, in India, create the illustrations (costly). However, when I self-published on KDP, I received my book and the cover was in color, but none of the illustrations were. When I checked, it was going to be too expensive to print the book with the colored illustrations.

I am interested in how you accomplished this. Did you have your paperback book printed, in color? If so, was it expensive?
