Half a World Away by Libby Gleeson is held by the greatest number of libraries Blackwood both wrote and illustrated (in watercolour and pencil)
Ivy Loves to Give (US edition: Scholastic, 2010), a 24-page picture book about a toddler, for ages two and up. The story features the "well-intentioned mistakes" of a "toddler who is learning where things belong". Blackwood won the annual
Kate Greenaway Medal from the
professional librarians for her part in the
picture book Harry & Hopper, written by
Margaret Wild and published by Scholastic in 2009. The award recognises the year's best-illustrated children's book published in the U.K. Her illustrations of Hopper were inspired by a dog she had as a child. The story features a boy and puppy who are "inseparable" until the puppy is killed while the boy is at school. "Blackwood's beautiful illustrations—laser print with
watercolour,
gouache and charcoal—add an appropriate layer of melancholy to Wild's clean, economical prose." ==References==
