Star Puzzle Block

I'm presenting the star puzzle quilt block to quilt guild this evening. I've seen this called a mosaic in one book. The block is comprised of 16 half square triangles and it has lots of potential as the placement of color make it look quite different.

In the first block, I used just 2 colors. For the next 2 blocks, I used 3 colors emphasizing the center pinwheel in one and the diamond shapes in the next. 

All of these are 8" finished blocks which quilt guild members are making this year. The donated blocks are put into quilts for veterans.
