Each piece is made as a hexagon. The pieces are jined together as you go. The pattern includes a photo tutorial on how to do this was well as how I changed colors so that it wouldn't show. I made a chart to show how the pieces go together.
The blanket can be made larger by making more pieces, which will require more yarn. It could also be made smaller by using a light weight yarn and smaller hook.
