Note that this pattern is excerpted with one of the brim variations from Fiber Trends AC1, Felt Hat with Brim Variations.

This felted hat has a round head-fitting shape and a simple rolled brim. The finished size is controlled by the size of the bowl used to block the felted hat. The pattern calls for the aran weight yarn to be used doubled, so a super bulky yarn could be substituted and knit singly.
