Well the brown one I made from here called a chunky Beanie, On the right side of her blog is a spot for Knitting patterns of hers. Look there. I made it out of a nice soft Alpaca for my husband but he did not like it at all so it needs to find a new home.
The colorful one on the bottom, my daughter made, I finished the crown a little bit for her. It was made from One skein of Nepal on Circular needles. It was a fast knit for sure.
Both of these hats fit very nicely and are easy to make.
