I Used the Magic Ring method. Or you chain 6 join with slipstitch & dc 6 into ring..

Shade A ... 1 dc this doesn't count as a stitch. Place a stitch marker here (easier to find start of each round & remember to place it on every sl st )

ROUND 2.. 1 ch ( this is not counted as a stitch its to give height)2dc in each stitch ..12 sts
ROUND 3..1 ch,* 1 dc, 2 dc in nxt stitch* repeat to end of round ...18 sts, join with sl st 
ROUND 4... ch 1 ,* 2dc 2dc in nxt stitch* Repeat* 24 stitches join with sl st

ROUND 5 Change to B chain 1, dc next 24 stitches. JOIN with a sl st.
ROUND 6.. Change to A ch 1, dc 24 stitches. JOIN with a sl St.
ROUND 7.. Change to C....chain 1, dc 24 stitches. JOIN with a sl st.
ROUND 8.. CHANGE to B ...1 ch , dc join round with sl st 
ROUND 9... CHANGE to C... 1 ch, dc to end of round. JOIN with a sl st.
ROUND 10...Change to A... Ch 1, dc to end of round. JOIN with a sl st.
ROUND 11 (Shell Edging)... Using C ch 2, 2 treble crotchet in same stitch * sl st next 2 stitches then treble 3 in next stitch* Repeat from * to * fasten off. 
TO FINISH... weave in ends and add a top knot by ch 30 using C fold 1 end to centre of chain ... fold other end to centre sew in place .. leave a long tail to attach to top of hat.

I pulled it through centre hole on top of hat and sewed in place on wrong side of the hat.
