Every year my family goes to Yosemite for the fourth of July, and when I was little, I remember spending all of my time playing in the Merced River that runs through some of the campsites. I remember rafting down the river. It's a different experience now, but when I was growing up California was going through a drought, so the river was pretty low. I remember places in the river where there were rocks everywhere... this block reminded me a bit of that.
The fabric is Amy Butler's Daisy Bouquet in turquoise from her Daisy Chain line. The block was freezer paper pieced.
