The leaf blocks are made out of prarie points with many different colors of fabric. If you have never tryed prarie points, you can see how there are done here on about.com
There is even a prarie point border.
I cut out eight assorted leaves and appliqued them onto the cream fabric. I used the raw edge method for the applique. I thought about hand stitching the leaves on ...for about a minute! Then I came to my senses and decided to get this done in August.
