Pinwheels for Celtic Solstice

I had a wonderful stitchy day yesterday.  I made progress on Celtic Solstice.  I have 40 Part II's done, and 160 Part III Half square triangles done.  I made up four pinwheel blocks last night before shutting down for the night.

I placed four onto a design board and them took them to the machine to stitch.  I have to keep my wits about me when doing pinwheels.  It is easy to flip those puppies the wrong way.
