The finished item can be used as a wall-hanging or afghan. We use ours for education purposes. It is a ‘100 square’. The squares across the top row represent the numbers 1 -10, the second row 11 - 20, and so on. The colours show which numbers, from 1 - 10, divide into the numbers represented by the squares. Each colour shows a different multiplication table. There are 10 colours that must be distinctly different from each other, plus a contrast colour for the lines between the squares.
