Dr D:
As usual I didn't explain very well. They are semi-circular fans, each 8 pieces of mottled anigre, butting up against multi-part banding.
To make the pieces, first I cut rectangles of the anigre, then cut each rectangle along a diagonal making a pair of 22.5°. 90°, 67.5° right triangles. The longest side of each of these triangles is the hypotenuse, opposite the right (90° angle), the slightly shorter side of each triangle is opposite the 67.5° angle, and the third side is much shorter than the other two.
I sand shaded the hypoteneuse (longest side) of each triangle.
To make the semi-circle, I set out 8 of the triangles, each with the shortest leg facing me and the sand shaded hypotenuse facing left. I put the middle length leg of the first triangle against the sand shaded hypotenuse of the 2nd triangle and taped them together. Then I put he middle length of the 2nd triangle against the sand shaded hypotenuse of the 3rd and taped them together, and so on until all 8 triangles were taped together making a semi circle. The flat side or diameter of the semi-circle had the unshaded middle length leg of the first triangle to the left, and the sand shaded hypotenuse of the 8th triangle to the right. So the diameter is half not sand shaded and half sand shaded. The alternative was to NOT sand shade the hypotenuse of the 8th triangle, so the entire length of the flat side of the semi circle would be not sand shaded.
After looking at an example of each option, I decided to sand shade the hypotenuse of each triangle, so that half the flat diameter of the semi circle is not sand shaded and half is. I'm not sure one option is better or worse than the other, in a way each looks slightly "off."
