I posted this pattern last year, and will be donating any proceeds from December 2010 to help a friend's friend and his family make it through a personal disaster: he was caught in random violence and needs reconstructive surgery.
This lacy tam is worked from the center outwards. The design spirals outward and flows into a ribbed brim. It looks more complicated than it is--if you know how to knit in the round, purl, knit two together, knit three together, and make a yarn over, you can make this hat.
Both charts and written out instructions (in abbreviations) are provided, along with suggestions for modifying the brim size to fit.
Other materials required include a darning needle for working in ends, about a yard of smooth, thin yarn for making a lifeline, and a plate for blocking (about 10 inches or 25cm in diameter).
