Half Measures was the result of a workshop at a Mathematics Conference in 1998. The delegates were challenged to design a series of eight squares to fit particular criteria.
Each set of eight had to show some form of progression and every square had to be exactly half pink and half blue. Each square also had to have 20 stitches, if knitted in the conventional way, and 28 stitches on the diagonal, if knitted from corner to corner.
I have always thought it would be interesting to take one of these blocks of eight and repeat it eight times, changing the colours, as another form of progression.
