I made Lucinda a promised bonnet for her birthday, too. I didn't follow a pattern, but just cut out one piece of fleece (folded on top) for the outside and another for the lining in roughly this shape:
I appliqued a duck on each side and sewed a scrap of trim along the front edge of the outside before attaching the lining, and then I added piping along the lower edge and i-cord ties (thank you, Millie) when I sewed the lining to the outside.
She's been wearing it non-stop, so I think she likes it.
She wanted me to take a picture of her pelican's cape, which I made on her request, using the very last scrap of leftover yellow fleece.
And guess who wanted a bonnet, too?!
Piper got hers two days later, made the same way, only with brown lining, black piping, different trim, and two SKUNKS in place of the ducks.
Two happy girls...
