When I was getting ready for my bath I sat on the edge of my bed and started to take the splint off. ! piece of figure of 8, yep, done, one piece around the back, yep done, but I couldn't find the 3rd piece. I called for help, he said "It's just this", I said "Aha, do it up again" and undid it myself and then was able to take my splint off alone.
See if I have remembered tomorrow night
