Sorry - I usually include the pattern names.
The purple one is an Ozark Star - free Fons & Porter pattern.
The upper left and bottom right are free Phillips Fiber patterns. On the bottom right is a Jewel Box Junior mini 10 point star. The upper left is a 12 degree pattern called Spring Blossom.
The lower left one I just made up and cut 60 degree triangles and went from there.
Oh, and the client decide they wanted the 10 point star in the colors of the 12 degree Spring Blossom.
