Ok, I am definitely going to use the "Parakeets" instead of the neutral/yellow for the sashing rectangles, there is just no yellow option that makes me happy. I'm only unhappy with about 1/4th of the blocks. It's all going work out fine.
So I now have a plan of attack. Today is to finish the remaining blocks. The future includes finish the setting triangle units. Cut the sashing rectangles. I'll be putting on the sashing randomly on each block in an L shape and won't do the final layout until I have it on. And then on to the borders. At this point I'm planing on doing the double sawtooth as designed. Isn't anything I would choose to do myself and once again I remind myself that is sort of the point. At least all the HST are made and now need something done with them so I don't back out completely.
Won't have any progress pictures for quite awhile. Here is the Yellow option and the expanded Parkakeet option I'm going with.
