The pattern is from Atkinson Designs, and it's called "Lucky Stars". I've got the first four block centres pieced, and they need to be trimmed down to 9.5". I'm going to go shopping tomorrow, so I've added a 9.5" square-up ruler to my shopping list, instead of struggling with a bigger ruler.
I'm stitching these little 'bonus blocks' using the triangles cut off from piecing the block centres. Instead of pinwheels, I pieced them into "broken dishes". Each one will finish at 2.5". It will be fun to play with them as I work on the bigger quilt.
