OMG I did that block early in my quilting life and about half of them came out wonky. I was not up to speed on templates and how to cut around them and my templates were too thick and made by a carpenter.
However the ones that came out good look great - I now love that block.
I suggest get that excellent 1/16" graph paper and plot it out. That way each template piece will come out to the correct size and you won't be measuring angles and worrying about 8/9 of anything.
Also I found the little triangles kept getting out of shape every time I looked at them.
Good luck and have fun with it - a super block. I sashed mine and made placemats.
