This is the last of the star blocks with Y-seams.
First I started off by creating the star blocks. (There are 4 in this one) I used the same method as I used on this block.
Once you've done that little piece, the rest is quite quick. :)
Here you see the star blocks and the 1/2 square triangles along with the other pieces set out and ready to go.
Here I've completed the centre pin wheel and the middle stripes. The remainder of the block is assembled as a 9-patch.
