Fleur is a 10 inch afghan square made with Stylecraft Special dk and hook size 4mm/G.
With Aran weight yarn it will give you a 12 inch square.
I used 2 colours but you can use as many or as less colours you want.
For 2 colours you need 1 skien per colour.
You will have plenty left to make a few more squares.
