The following is a graph for a blanket.
I'm currently working it with a H-5.00mm hook and worsted weight yarn in the C2C method (3 ch, 3 DC for each block). The dimensions are approximately 30"x30" for just the graph. I'm going to be adding a border on mine to get it slightly bigger.
Below is a PDF and spreadsheet download, as well.
