Here's a snapshot of my initial experiments in fixing up the knee JCMs after creating conforming thigh-highs in the fitting room. Right knee fixed, left knee not, in case that was unclear. :-)

Question: does anyone know an easy way to mirror a conforming figure, so I could make, say, the right sock as an  individual figure and then mirror it to get the left sock? Asking for a friend (named Antonia).
