My block is to measure 12 1/2" at this point, close on the first one. My drawing on paper I did, started as a finished 12" square block. My strip pieced units are 6 1/2" (unfinished size) from point to the bottom row. I am fuzzy and do not want to lose my points. The blocks are going to take weeks to piece together. I thought I would make a large lap quilt but now I have decided to go for 96" square. That is 8 by 8 blocks, for a total of 64 blocks.
Lots of cutting has gotten done. I may need a little more to get my 64 blocks.
Here are some cutting demo photos. I first cut a strip 5 1/4" then cut using my star point template on my 22.5 degree ruler. The bottom of the template is lined up to the square corner of the fabric.
I then cut the next one, first cutting the strip at right angle 3 inches from the angle. The side of this template was 3" for the angled side. I know I am not saying this just right but maybe you will get what I say if you did want to try this block and cut it like I did.
I must tell you I have found out the web quilt my mom did many years ago was not the same angle as this one. Her quilt used hexagons not the eight sides mine has.
I love all your comments Thank You all. Please let me know if you have questions.
