Free Quilt Block Pattern
I don't know if Pinwheel Star is the correct name for this quilt block. I just came up with it while playing around with the colours in another block. Right away, I noticed the pinwheel in the centre of the block as well as the star that forms around it -- hence the name I gave it. This is an easy block to construct because it contains only basic shapes -- the square, half square triangles and flying geese units.
If you happen to know if there is an actual name already for this block, please let me know.
