Jigsaw was a BBC show aimed at children between the ages of 4 and 7 that combines elements of puzzle solving and entertainment, which was broadcast from 16 July 1979 until 24 May 1984. Written and directed by Clive Doig, the show was presented by mime artist Adrian Hedley, Janet Ellis and "Jigg" - a giant floating orange jigsaw piece, voiced by John Leeson. Ellis left in 1983 to become a Blue Peter presenter, at which point she was replaced by Dot, aka Julia Binstead.
