'Square Deal' woollen knitting 91x83cm showing minimum number of squares of different sizes in a square, 1996.

The acrylic knitting shows the minimum number of squares of different sizes that can be fitted into a square. A square which can be dissected into a number of smaller squares with no two equal is known as a perfect square dissection. It was thought they were impossible to construct, until T H Wilcox published a 24-square solution in Fairy Chess Review in 1948. Thirty years later a smaller version was discovered by A J W Duijvestijn in which 21 squares of different sizes were fitted into a square. It is this solution that Ashforth has reproduced.
