One of my students said she felt she was in New York, looking down on tall buildings - hence the name Tower Blocks.

The optical illusion is so convincing another young student looked underneath to find ‘the other cube’. He was sure there were eight cubes in each block but could only count seven.

The afghan uses three main colours with various shades of grey to give the light and shade effects. Use the yarns of your choice.

A colouring sheet is included so that you can keep track of your own colourways before you begin.
