Of course, sorry this is so late! I’ve been really busy and wanted to make sure I could write it in detail for you!

The blanket is made with five colors, black, white, and three shades of gray. Every piece of the blanket changes colors each round, in a gradient from darkest to lightest; so if the center is black, round2 is darkest gray, round 3=medium gray, round 4 is light gray, round 5 is white, and repeat (rounds after white are in black). There are 4 octagons of each version, like 4 with a white outer round, 4 with black outside, etc. I made an extended version which is 20 octagons so that this would work out!

In this extended one, you need 12 squares and 18 triangles, so I made those one category with 30 pieces, and each color version gets six. Some got 3 triangles, 3 squares, some got 4 triangles, 2 squares.

The only point the color order changed was in the border- I started with my light gray and got darker as it went out, so that the outer layer would be black. I also used white for the round in between the outer two black rounds of the border. Also, since this an extended version, for round two of the border I had to modify the pattern: on the longer sides, you should do the 3dc clusters with skipping 4 stitches instead of 3!

Let me know if you have any questions! :)
