Alysha's Flower Hat Pattern

I made this hat for a four-year-old girl named Alysha, who is the neighbour of one of my close friends. Alysha was diagnosed with leukemia in November 2008 and needs a bone marrow transplant to be cured. Her situation has inspired Operation Alysha, which encourages people to donate blood products and to join the the Canadian Blood Services' national bone-marrow registry, One Match. Alysha is undergoing chemotherapy right now, and I thought she could use a new hat to keep her head warm until all her hair grows back.

I used an easy-to-wash acrylic yarn, Bernat Satin Solids, to make this hat, but any worsted-weight yarn would work. I hope you enjoy using this pattern. Comments are always welcome.

Materials

Bernat Satin Solids, 1 100 g (3.5 oz) skein each of Maitai 04732 (MC), Sunset 04605 (A) and Sapphire 04141 (B).
Note: a full skein is needed only for main colour (MC); small amounts of any worsted-weight yarn may be substituted for colours A and B. Approximately 110-140 m (120-150 yds) are needed in all.

4.0 mm crochet hook
3.75 mm and 4.5 mm double-pointed or circular knitting needles
Note: If using circular needles, you can use either a 40 cm (16 in) needle for the body of the hat or two circular needles simultaneously. For shaping the crown, you will need double-pointed needles or two circular needles.
