The idea of mixing yarns to create new, in-
The original version was a disaster. The squares were made individually, by the diagonal method we had used so often before, and then the squares were put together at random. It was impossible to identify how many different squares there were. It became known as Double Trouble and is a very good way of showing why mathematicians should be systematic and methodical.
We started again, having decided that basic strong colours were all we needed. One advantage of using these colours is that they are available at even the smallest yarn shop. The ten colours can be seen on the diagonal from top left to bottom right, where two strands of the same colour are used. Every other square is a mixture of two colours. Every square in the top row and the extreme left column has dark pink included. Every square in the bottom row and extreme right column has pale pink. At two corners the bright pink and pale pink coincide so there are two squares with the same combination of colours.
In addition to the diagonal solid colours there are 45 combinations, making 55 in all. The solid colours were knitted first with the legs of L shapes being knit in strips from picked up stitches, in much the same way as Some Square Over the Rainbow.
We once exhibited Double Vision in a chapel, between two stained glass windows. It looked very much at home. Many people have commented that it is reminiscent of a stained glass window.
When I bought the yarn for this I really wanted each of the ten yarns in both double knitting and 4 ply weights so that every square would be different even though there would be pairs of squares using the same two colours. Unfortunately we had to settle for just double knitting yarns.
