Just looked at your stars again... IF these are 12.5" blocks, all the triangles in the second block would be 2.5" finished. You need to make HSTs that are 2.5" finished. Likewise, the snowball corner triangles in the North, South, East and West blocks are also 2.5" finished. Center square is 4.5" the 4 white snowballed squares are 4.5", before the corners are applied.
The kimono star would have 4 corner blocks at 4.5" square. The center is cut 3" square, and cut two white pieces 3"x1.5", and two pieces 4.5"x1.5".
Each North, South, East and West blocks would be a 4.5" HST and a 4.5" Quarter Square triangle. The kimono stripe looks like 1.2" finished, so you would need to start with a 1" strip. Add stripe, and trim your pieces to the proper size with a ruler, so that the total square ends up 4.5".
Clear as mud?
That's how I would do it, anyway. I have no EQ program.
