I recently made this bonnet,using the fabric from an old pair of green linen pants.
We have much fancier bonnets, that are basically good-for-nothin'-except-looking-cute. Which I love. But I wanted one that would protect Baby Girl's sweet skin when we are outside, which is often. So this bonnet was originally to be strictly utilitarian and sewn together in a hurry...extra long brim for protection from the sun and wind. And the color "goes" with pretty much anything.
But then, I couldn't resist sewing a doily on the back of it, and putting a blue polka-dot grosgrain ribbon on it too. And crochet at the brim tip.
