Hello! Thank you, David for sharing your class. I learned a lot from it. I was struggling to format my children's picture book in Kindle, so I tried your methods and it worked! :)
I was able to publish my own picture book in Kindle just how I like it.
Here is the link of my book:https://www.amazon.com/Lets-Learn-Numbers-Colors-Counting-ebook/dp/B06XD384PZ/ref=sr_1_1?ie=UTF8&qid=1490232899&sr=8-1&keywords=lets+learn+numbers+and+colorsThank you so much!
