First off, gorgeous projects and good for you for show and tell!
I think the dark makes the most satisfying ending, but I like either of the middle ones.
Is nice (but maddening) when we have multiple good options!
As for me, I have a number of bindings to make on the to-do list, I pretty much always make French double fold bias tube bindings. Two have had their lines drawn and are ready to be turned into a tube and then cut. The third is prewashed but no further. I always like to put the completed tops into the "ready for quilting" box with their backing and bindings made. I wrap the binding around pieces of cardboard that are 12-18" long, let's me easily count the yardage that way too!. That third one is for a top that's been done for a few years and I was surprised that it didn't have a binding with it so while not done I am close.
