Here is Dear Jane block L13 or Harvest Moon. This is my favorite type of block to make. Those of you making a circle a day might be less fond of this block.
First, I made two four patches where each four patch is at least 1/2 inch larger than the circle they will become. I carefully center and mark the circle on the back. Then I cut the circle out, baste around the seam allowance, and gather the seam around a Karen Buckley mylar circle.
Here are the prepared circles. I carefully center the largest circle on the background fabric.
Then I lay the smaller circle on top of the larger circle. Last but not least, I applique the two circles down. (I will trim away the excess fabric underneath later. If I remember.)
Molly thought it might be easier to understand the construction using cats. Molly says she represents the center circle (aka the center of the universe), while Buddy is the merely decorative outer crust that should hold still when the inner core bites him.
