Colorful granny squares in progress

My latest crochet blanket project uses the basic granny square pattern and 12 different colors to make 24 different squares. A color is used only once per square and for the same row on only 2 squares. For instance, light blue is used only once in a square, and light blue is used for row 1 for only 2 squares and used for row 2 for only 2 different squares, etc. It's been fun playing with 12 different colors!

I now have 24 uniquely-colored squares of 7 rows each. I plan to add 2 rows of black to each square, join them, and add a border. Before joining, I will decide whether to make 2 lap blankets with 12 squares each or one large blanket with 24 squares. The decision is based on what I would plan to do with the 24-square blanket.
