Arrange the Granny Squares into a rectangle of 2 rows of 4 squares each. Hold 2 Squares with WS together (so RS of each Square is facing out) and join B with a sl st at beg of one edge. Working through both thicknesses, sc evenly across to join Squares. Continue to join edges in this manner, fastening off and rejoining B as needed, until all edges have been joined.
In same way, join ends of this rectangle to make a ring.
Lower Edge Trim
With the RS facing, join B with sl st anywhere along one edge of ring, sc evenly around edge; join with sl st in first sc. Fasten off.
Working along opposite edge of ring, work as for Lower Edge Trim.
At top of Hat, bring 4 crocheted joining 'seams' together and secure with a few sts. Note that open spaces will remain at top of Hat.
Weave in ends.
