Here is the link to the pattern: http://fringecrochet.blogspot.com/2011/01/crochet-cable-hat.html

Hats are more aptly described as an art rather than a science. For this reason, I think of hat patterns as suggested guidelines rather than a formula to be followed without question. The finished object will be the result of several factors including the yarn selected for the project as well as the tension/gauge and style of the individual crocheter.

This hat contains 12 small crochet cables and is worked in the round. Beyond the basic structure, it can be completed with or without a folded brim, and can be adjusted to be taller or shorter, as desired. Particularly as you reach rounds 25 and 26, you may wish to adjust according to your vision of the finished object. The same applies to the ribbing rounds that finish the hat. Most importantly, enjoy the process and be creative.

The yarns listed above are suggestions.
