For my granddaughter's fourth birthday, which is in July, I crocheted a silly-fun sunhat for her. I liked the yellow yarn, one of the crayon colors.
Here's the pattern I used: Free Ruffled Brim Sunhat Pattern… with thanks to the designer. It was a little bit big, but I'm sure she'll grow into it. In the meantime it will look great on a teddybear, no doubt.
The flowers were just experiments, and I honestly don't recall how I did them. I tied a piece of yarn to mark the center back, which makes it easier for kids to get it on right.
