You can find printable bookmarks for specific books and authors. Here are a few I've found.
Bookmarks from The End by David LaRochelle:
You can print bookmarks to color from his fun picture book, The End. The book is a fantastic upside down fairy tale that starts with "and they all lived happily ever after" and ends with "once upon a time." The printable bookmarks include backwards writing and fairy tale illustrations. We had fun with this in kindergarten!
Dog Bookmarks with Gary Paulsen Quotes:
Each one has a dog graphic and a quote from one of Gary Paulsen's dog books, perfect for following up a Gary Paulsen booktalk.
Diary of a Fly Printable Bookmarks:
I'm sure you love Doreen Cronin's series as much as we do: Diary of a Worm, Diary of a Spider, Diary of a Fly. They are so funny! Here are some printable black and white bookmarks for Diary of a Fly. There is not a huge area to color, but it does include several facts about flies, good for insect studies!
