Maxi Puzzle: 360x250mm (14x10") and contains 250 pieces, including Wentworth 'whimsey' pieces. Picture by Julia Rigby. The Wentworth Jigsaw Company has been producing exquisitely crafted wooden jigsaw puzzles since it was founded in 1994. Using computer controlled lasers and state of the art technology, Wentworth has become known for its quality and design. All Wentworth Jigsaws include their famous 'whimsey pieces'. These are specially shaped pieces that are cut into the puzzles "on a whim." The Whimsy pieces are cut by a Victorian hand cutter and Wentworth are one of the only companies still producing these unique puzzles. We also stock many of Wentworth's favourite designs from its extensive back catalogue.
