I have seen this block used in many of the quilts shown at the Kalona Quilt Show and Sale held yearly here in Iowa but always with the name of Dahlia not Missouri Daisy.
Kalona is an Amish community so when I found the this block pattern at Quilter's Cache called Amish Dahlia that made perfect sense to me.
Here's a beautiful example of an Amish Dahlia or Missouri Daisy quilt from Quilting in Oz. Be sure to read the story behind this quilt that was fifty years in the making.
I did not make this block for my sampler. I think it's too complicated for a 6" block.
