Here is how I crocheted it:
I’ve made two stitches, then done 6 single crochets in the first stitch.
For the next row I’ve made 3 stitches, then did 2 double crochets in every stitch of the circle.
From then on I’ve use triple crochets for every row and done 1 addition of sitch for every three stitches. (2 tipple crochets, then 2 more in one stitch, etc.). That I’ve done to make a big enough circle.
Then I started to decrease the number of stitches, decreasing every 5th stitch. Kept on crocheting like this for 4 rows.
I’ve crocheted rib knit, doing front and purl triple crochets in turn. I’ve done two rows of this type. Then I joined the hat with the rib knit and crocheted the flower.
That’s how it looks on her
