Hi Marion. I must have missed this thread before. I'd suggest cloth tape - the thin stuff used for bandages. You can get it in a size that's just the width of a fingertip, and it will wrap better than stiffer tapes.

You could probably buy some sort of small dot stickers, but I don't know how well they'd stay on. They also make a glue stick that's the same stuff used on sticky "post-it" notes, so it's removable. (It might also come off too easily.)
