Greenleaf Baby Hat
Uses a little less than one skein. Pattern includes info on making a larger or smaller size and a different brim style.
This pattern is no longer available free. I made a few improvements and created a pdf file.
The second example picture shows the hat with 2 x 2 rib instead of roll brim, in dk weight, instructions included for adaptations.
