Ashley Wolff has illustrated and written dozens of books. She is always trying out new media if she thinks it will serve the story. Collage was perfect for Compost Stew. Read more about her at http://ashleywolff.com/.
Here's a photo of Ashley on the beach with seaweed. She's always so creative, one of her fave things to do is to collect little things that wash up on shore and make Beach Faces out of them!
And I love this last Beach Face with her sweetie, Tula. (R.I.P.)
