Finally! This pattern did my head in a little bit...in a good way. Figuring out where the measurements come from, and above all, the order of the steps, is a challenge in itself. In Islamic geometric patterns, the order of the steps is so necessary as so many lines and circles are dependent on others. Thank you for the idea for this design @artofislamicpattern! As you can see, I’ve extended the outer rosettes instead of making the outer edge a decagon, but I think when I go through and transfer it, I’ll make it a decagon as I think it is more visually pleasing. Whew!
