I've done it! I don't have pictures on me, but I've done it!! 3 times now, actually.
I did it with needle-nose pliers meant for jewelry making. I always loosen the hair by poking through the plugs with needle or pushpin, then when I grasp onto a chunk of hair on the inside with the needle nose pliers, I twist like crazy. Any stubborn bits of hair that are left I poke through with the needle or pushpin I used initially...if that makes sense! It's a pain, but it CAN be done on a CMC!
Good luck with your Sweetie Belle!
