I saw a display of coke cases in a mosaic of Mickey Mouse at a local Winn Dixie grocery store. This was made with 2 inch Granny Squares.

In the graph I used http://www.garrettbartley.com/graphpaper.html

I revised the ears quite a bit, so it varies from the finished product. I don’t remember how many skeins of yarn I used, when I first made it but what I do know is that one skein of yarn makes 60-62 (2 inch) granny squares with a H (5.0mm) hook.
