I wanted to share something that came up in discussion a couple of weekends ago when knitting with some friends. One person had seen an afghan/lap throw done in the manner of a Sudoku puzzle. There were nine colors with a number (1-9) assigned to each color. You take a solved Sudoku puzzle and arrange the knitted or crocheted squares of colors according to where the numbers fall.
There was a lot of discussion of putting black or dark borders around each square or not or just putting the border around the outside or doing both.
