sunbonnet sue help

That title is there just to freak out my mom who has serious issues with Sunbonnet Sue quilts.

We're reading Little House on the Prairie at our house (with some effort by me to put everything into a cultural context), and Mia wanted to see a covered wagon so we went out to the End of the Oregon Trail Interpretive Center yesterday. She was absolutely thrilled and loved every minute, corny multi-media presentation and all, but what she keeps talking about are the sunbonnets she tried on in the gift shop.

Does anyone know of a free child's sunbonnet pattern? I've googled to no avail. Thanks!
