I ran out of weeks for the Rainbow Scrappy Challenge, and am making a red lion before the new month begins. As you can see, the first step is to make a wedge circle, aka dresden plate for the mane. Then I make a block face that will be inserted as a circle into the mane.
And the Stonefields quilt by Susan Smith calls for three of these star blocks (crosses within a circle within a star.) To make these, I first machine piece the plus blocks. Like the lion's face, these will become circles within a circle.
And here are two completed vintage butterfly blocks.
