Welcome from another Michigander....
I think the Holly Hobbie is modeled after the classic Sunbonnet Sue quilt image. You should be able to find quilt blocks of sue's image on several quilting sites.
I plan to make one of these this summer...(another friend wants to make one, too) when I'm at our our cabin. I have a pattern for 12 months of Sunbonnet Sue but have to find it in my sewing area..... hope I didn't leave it up north.
If I find it this week, I'll pm you..... I could scan the pictures and send it via email.
