From the pattern description in Piecework Sep/Oct 2010:

“One of my favorite children’s books is Esperanza Rising by Pam Munoz Ryan (New York: Scholastic, 2000), and this bookmark was based on the crocheted afghan that follows Esperanza throughout her year of trials and growth. The colorful variegated thread gives the bookmark a bright and scrappy look without all the ends to tuck in!”
