I’m reading a couple of rhyming picture book manuscripts for a beginning writer and pulling resources that may be of use to her. They include:
Rhyming Picture Books: For Those Who Must by Margot Finke from the “Musings” Archive in April 2004. This page offers a number of really on-target links. I especially like:
“To Rhyme or Not to Rhyme” by Dori Chaconas from Smart Writers Journal in April 2003.
